Twelve 6 fl oz cups is 72 fl oz of water, which takes about 117 g of ground coffee at the standard 55 g per litre. If your machine’s 12 cups total 60 fl oz, use about 98 g. That’s roughly 23 or 20 level tablespoons, but spoons and scoops vary, so weigh it if you can.
At 60 fl oz, the standard 98 g is more than 1.6 times the 12 tablespoons (60 g) in Mr. Coffee’s own chart: the manuals run light (details below).

How much ground coffee for 12 cups, in grams, ounces and tablespoons
A “12-cup” machine isn’t a fixed size, so there are two answers.
| If your 12 cups are | Water | Coffee at 55 g/kg | In ounces (weight) | Level tablespoons |
|---|---|---|---|---|
| 12 × 6 fl oz = 72 fl oz (the coffee cup) | 2.13 L | 117 g | 4.1 oz | about 23 |
| 12 × 5 fl oz = 60 fl oz (Cuisinart, Mr. Coffee) | 1.77 L | 98 g | 3.4 oz | about 20 |
If you want a single sentence to remember: 55 g of coffee per litre of water, or about 10 g per 6 fl oz cup and 8 g per 5 fl oz cup. A 12 oz bag of ground coffee is about 340 g, which is just under three 72 fl oz pots or about three and a half 60 fl oz pots.
Coffee calculator for any number of cups
Set the number of cups, your cup size and the strength. The calculator uses the same 55 g per litre standard as the tables on this page; tablespoons are approximate.
Use 117 g of ground coffee (about 4.1 oz by weight, or roughly 23 level tablespoons) for 2129 mL (72 fl oz) of water.
Tablespoons assume 5 g per level tablespoon, Mr. Coffee’s figure; a spoonful’s weight varies with grind and roast, so weigh if you can.
How many ounces is a 12-cup coffee maker?
Twelve cups add up to 60 fl oz or 72 fl oz of water, depending on whose “cup” is being counted. Three are in play, and they are easy to mix up:
- A US measuring cup is 8 fl oz: NIST’s conversion factors list it as 236.588 mL against 29.5735 mL for a fluid ounce. The 12-cup machines below don’t use it.
- A coffee “cup” is 6 fl oz, the unit the NCA’s Golden Ratio is written in: “1 to 2 tablespoons of ground coffee for every 6 ounces of water”.
- Cuisinart and Mr. Coffee count a machine “cup” as 5 fl oz. The Cuisinart DCC-1120 instruction booklet, listed on Cuisinart’s own manuals page, describes a “60 oz. (twelve 5 oz. cups) coffeemaker”. Mr. Coffee’s product pages for its 12-cup machines (Hot & Iced, 3 Ways to Brew) both say “Capacity: 12 Cups (1 cup = approx. 5 fl oz / 148 mL); 60 fl oz / 1.774 L water capacity”.
The 72 fl oz size needs 20 per cent more coffee than the 60 fl oz one. Nobody can tell you which you own, but your machine can. Fill the carafe to its 12 mark with cold water, tip it into a measuring jug or onto a scale (1 mL of water weighs about 1 g) and write the total on a sticky note. The dose follows the water you put in, not the coffee that comes out, and Mr. Coffee’s manual notes that “Some water will be absorbed into the coffee grounds and water filter during the brewing process.”
How many tablespoons of coffee for 12 cups?
At the standard strength, about 20 level tablespoons for a 60 fl oz machine and about 23 for a 72 fl oz machine. That is roughly 1¼ to 1½ US measuring cups of grounds, or 60 to 70 teaspoons, since NIST’s factors make a tablespoon three teaspoons and a US cup 16 tablespoons.
You may see 24 tablespoons (1½ cups) quoted for 12 cups. That is the strong end of the NCA’s Golden Ratio for a 72 fl oz pot, 2 tablespoons for each 6 fl oz.
Those counts assume 5 g per level tablespoon, which is Mr. Coffee’s figure: the chart in its 12-cup manual reads “1 level tablespoon (tbsp) = 5 gr./0.17 oz.” Treat it as approximate: a heaped spoon holds more, and how much a spoonful weighs also depends on the grind and the roast (see coffee roast levels), so the tablespoon is the least reliable number on this page.
| Source | Tablespoons, full pot | Grams |
|---|---|---|
| SCA standard, 55 g/kg | about 23 (72 fl oz), about 20 (60 fl oz) | 117 g, 98 g |
| NCA Golden Ratio, 1 to 2 tablespoons per 6 fl oz | 12 to 24 (72 fl oz), 10 to 20 (60 fl oz) | about 60 to 120 g, about 50 to 100 g |
| Mr. Coffee manual chart | 12 (60 fl oz) | about 60 g |
| Cuisinart DCC-1120 booklet | 12 (“1 level scoop” per cup), limit 15 (60 fl oz) | about 60 g, limit about 75 g |
We haven’t weighed tablespoons of coffee on this site’s scale, and this page won’t publish a measured figure it didn’t measure. If you own a 0.1 g scale, weigh three level tablespoons of your usual grind once and divide by three: that number, for your coffee, beats every general figure here. Our page on coffee tools and accessories covers scales.
How many scoops of coffee for 12 cups?
With a one-tablespoon scoop, the standard dose is about 20 scoops for 60 fl oz and about 23 for 72 fl oz. The answer depends on your scoop, and we could confirm only one maker’s scoop size from its own paperwork: Cuisinart’s booklet counts “15 scoops (15 tablespoons)”, so its scoop is one tablespoon. Mr. Coffee’s chart is written in tablespoons, not scoops.
If your scoop holds two level tablespoons, halve those counts: about 10 for 60 fl oz and about 12 for 72 fl oz. To find out what yours holds, level it with your usual coffee, weigh it once and divide the dose by that weight.
Mr. Coffee and Cuisinart 12-cup coffee makers: what the manuals say
Both manuals dose by the level tablespoon or scoop, and both come in under the standard ratio, as the table above shows.
Cuisinart 12-cup (DCC-1120)
The booklet sets a limit: “The maximum capacity for ground coffee is 15 scoops (15 tablespoons) for this 60 oz. (twelve 5 oz. cups) coffeemaker.” Its starting suggestion is “Add 1 level scoop of ground coffee per cup. Adjust the amount according to taste.” That makes 12 tablespoons for a full pot.
A standard-strength dose for the full 60 fl oz is about 20 level tablespoons, roughly 30 per cent over that limit. The booklet doesn’t say how many grams the limit is, so we can’t say where the basket really floods, but it ties overflow to coffee that is “too finely ground”. If the basket floods, grind coarser before you cut the coffee.
Mr. Coffee 12-cup
Mr. Coffee’s manual for its 12-Cup Programmable Coffeemaker with Strong Brew Selector (models BVMC-MMX23, BVMC-MMX26 and BVMC-MSX23-NLY) has a “Suggested Coffee Measurement Chart”. It pairs 12, 10, 8, 6 and 4 cups of water with the same number of tablespoons of ground coffee, adds “Use more or less coffee to suit your taste.”, and warns “Using fine coffee or decaf may cause overflow.”
Both makers start at 12 tablespoons for a full pot. At Mr. Coffee’s 5 g per tablespoon that is 60 g, about 60 per cent of the 98 g the standard ratio gives for the same 60 fl oz (33.8 g per kg of water against 55). The standard dose is simply more coffee: about 20 level tablespoons rather than 12.
How much coffee for 10, 8 or 6 cups?
Scale the dose with the water.
| Cups | If a cup is 5 fl oz | If a cup is 6 fl oz | Mr. Coffee chart |
|---|---|---|---|
| 12 | 98 g (about 20 tbsp) | 117 g (about 23 tbsp) | 12 tbsp |
| 10 | 81 g (about 16 tbsp) | 98 g (about 20 tbsp) | 10 tbsp |
| 8 | 65 g (about 13 tbsp) | 78 g (about 16 tbsp) | 8 tbsp |
| 6 | 49 g (about 10 tbsp) | 59 g (about 12 tbsp) | 6 tbsp |
| 4 | 33 g (about 7 tbsp) | 39 g (about 8 tbsp) | 4 tbsp |
A single 12 fl oz mug works out at about 20 g, or about 4 level tablespoons. Both makers treat small batches as a special case: Cuisinart’s booklet says “Push the 1–4 cup button if you are brewing fewer than 5 cups.” and Mr. Coffee’s chart says “For best results, brew 4 or more cups of coffee.”
How much whole-bean coffee for 12 cups?
The same weight: 98 g of beans for a 60 fl oz machine or 117 g for 72 fl oz, weighed before you grind so you don’t have to guess how much a scoop of beans holds. If you would rather count whole beans than weigh them, see how many beans per cup of coffee, which works from the same 55 g/kg figure.
How do you make a 12-cup pot stronger or weaker?
Stronger means more coffee. In a ratio written as 1:18, the second number is how many parts of water you use per part of coffee, so a smaller number (1:15, 1:14) is a stronger cup and a larger one is weaker. To strengthen a pot, add coffee; don’t take it away (Mr. Coffee’s chart suggests heaping tablespoons for a bolder cup). Every standard-strength figure on this page is calculated from 55 g per litre, never from a rounded 1:18.
| Ratio | Coffee per litre | 60 fl oz carafe | 72 fl oz carafe | Result |
|---|---|---|---|---|
| 1:15 | 66.7 g | 118 g | 142 g | Noticeably stronger |
| 1:16 | 62.5 g | 111 g | 133 g | Slightly stronger |
| 55 g per litre (usually written 1:18) | 55 g | 98 g | 117 g | The reference point |
| 1:20 | 50 g | 89 g | 106 g | Lighter |
Pour-over and French press are usually brewed stronger than drip, commonly 1:13 to 1:16 for pour-over and 1:10 to 1:16 for French press. Those are different methods with different contact times, not disagreements with the drip figure above. If you drink your pot with creamer, how much creamer in coffee covers the other half of the measurement.
How do you make a 12-cup pot of coffee?
The NCA’s steps for drip coffee come down to four. Here they are with this page’s quantities filled in:
- Measure the water. Fill the carafe to its 12 mark with cold water and pour it into the reservoir.
- Weigh the coffee at 55 g per litre of that water (117 g for 72 fl oz, 98 g for 60 fl oz, or the tablespoon counts above), then grind it just before brewing, to the size described below.
- Set up the filter. Put a paper filter in the basket, fully open and seated, or use a permanent one if your machine takes it.
- Add the coffee, close the lid and start the cycle.
Time, temperature, grind and water
- Time. The whole cycle, not each cup. The NCA gives “5 minutes, approximately, of contact between coffee and water” for drip.
- Temperature. SCA 310-2021 section 6.2 requires the slurry to reach 90 to 96 °C and stay there for the rest of the cycle. See our page on the best temperature for French press coffee for the full range with its source rather than a second copy of it here.
- Grind. The NCA says to “start with a medium grind, then adjust as needed” and lists drip as “Medium (like kosher salt)”. Cuisinart’s booklet recommends “a medium-fine grind” for the DCC-1120 and warns that a grind that is too fine “may also clog the filter” while one that is too coarse lets the water “pass through too quickly”. Check your own machine’s booklet.
- Water. The NCA’s advice is “Use cold water, filtered if possible, and avoid distilled or softened water”. For its brewer tests, the SCA standard specifies fresh cold water at 17±3 °C, free of chlorine, at 50 to 175 ppm calcium hardness.
Where does the 55 g per litre figure come from?
The reference figure is set by SCA Standard 310-2021, Home Coffee Brewers, which comes out of the SCA’s Certified Home Brewer program. Section 7.1.5 reads: “The standard brew ratio of 55 g of coffee per 1.000 kg of 17±3°C water shall be used for both batch sizes as per 7.1.1.” Section 6.7 requires manufacturers to print “a coffee/water ratio of 55 g/kg (or its equivalent in other units)” in the instructions that ship with the machine. Dividing through, 55 g per 1,000 g of water is 1:18.2 by weight, which is why it is usually written 1:18.
One caveat on that link: the SCA now offers this standard only to members, behind a login, so the copy above is an SCA-branded PDF hosted by CoffeeGeek. We have checked that the quoted sentences appear in it verbatim, and this page will be re-pointed if the SCA makes the standard public again.
The NCA states the same idea in kitchen units as the Golden Ratio: “1 to 2 tablespoons of ground coffee for every 6 ounces of water”. The strong end of that range is the SCA figure: 6 fl oz of water weighs 177.4 g, 5.5 per cent of that is 9.8 g, and two level tablespoons at Mr. Coffee’s 5 g each is 10 g. The two agree to within about 2.5 per cent; only the units differ.
Corrections to earlier versions of this page
Earlier versions of this page gave dosing figures that could not all be true at once.
- An earlier version of this page said that at 1:18 you need “about 4 ounces, which is roughly 1.25 cups or 20 tablespoons”. That was wrong: four ounces by weight is 113 g, but twenty tablespoons at 5 g each is 100 g, so the page was quoting a weight for one carafe size and a volume for another.
- An earlier version said that at 1:15 you need “approximately 3/4 cup” of ground coffee. That was wrong: 3/4 cup is 12 tablespoons, about 60 g, which is less than the page’s own 1:18 figure. A 1:15 brew is stronger than a 1:18 brew because it uses more coffee per litre of water, not less.
- An earlier version said, in its FAQ, “For 12 ounces of water, you’ll need about 2 tablespoons of ground coffee, if you prefer a strong brew.” That was wrong: two tablespoons per 12 ounces is one tablespoon per 6 ounces, the weak end of the National Coffee Association’s range and about half the dose the rest of the page recommended. It was labelled as the strong option.
- An earlier version said the brew cycle “should take about 5 to 6 minutes per cup”. That was wrong: for a 12-cup pot that is 60 to 72 minutes. The NCA’s figure for drip coffee is “5 minutes, approximately, of contact between coffee and water” for the whole brew, not per cup.
- An earlier version said a full-strength 60 fl oz dose “sits close to” Cuisinart’s 15-tablespoon limit. That was wrong: it is about 20 level tablespoons, roughly 30 per cent over.
- An earlier version gave 105 g for a 72 fl oz carafe at 1:20. That was wrong: it is 106 g.
- An earlier version said that adjusting the grind “changes extraction without changing strength on paper”, and that a machine taking much longer than about five minutes “is usually a scale or flow problem rather than a dosing one”. We could not find a source for either claim and have removed both.
Thank you! Best information I’ve ever read!
