Convert between coffee scoops, tablespoons, and grams with exact water amounts. Batch sizing for 1-12 cups with strength presets and unit conversion.
"How many scoops of coffee do I put in?" is the most Googled coffee question in America. The answer depends on your cup size, your scoop size, and how strong you like it, but a reliable starting point is 2 level tablespoons (about 10g) of ground coffee per 6 oz of water. Most standard coffee scoops hold about 2 tablespoons, so it's roughly one scoop per 6-oz cup.
The confusion comes from inconsistent "cup" sizes. A "cup" on most American coffee makers is 5 oz (not the standard 8-oz measuring cup). So a "12-cup" coffee maker actually brews 60 oz, not 96 oz. This calculator resolves that ambiguity: enter how many actual cups (your chosen size) you want, and it calculates exact measurements in every common unit: grams, tablespoons, scoops, and ounces of coffee — alongside the precise water amount in cups, ounces, and milliliters.
Whether you're measuring with a scale, a tablespoon, or the scoop that came with your coffee maker, this calculator gives you consistent results. It also handles batch scaling for everything from a single pour-over to a full 12-cup drip machine.
Use this to turn cups, scoops, or tablespoons into a precise brew recipe. It is especially useful when scaling from one mug to a full pot.
Standard: 10g coffee per 6 oz (177 mL) water. Per cup: Coffee (g) = Cup Size (mL) ÷ Ratio. Conversions: 1 tablespoon ≈ 5.5g ground coffee, 1 standard scoop ≈ 10g (2 tbsp), 1 oz coffee weight ≈ 28.35g. Coffee maker "cup" = 5 oz = 148 mL.
Result: 40g coffee (7.3 tbsp / 3.6 scoops), 24 oz water
4 cups × 6 oz = 24 oz (710 mL) water. At 1:17.7 ratio: 710 ÷ 17.7 = 40g coffee. That's 40 ÷ 5.5 = 7.3 tablespoons or 40 ÷ 11 = 3.6 scoops.
Not all coffee scoops are equal. **Standard coffee scoop:** 2 tablespoons (~10-11g). **Keurig/Cuisinart scoop:** varies by model (8-12g). **Tablespoon measuring spoon:** 1 tablespoon (~5-6g). **"Heaped" vs "level":** A heaped tablespoon can hold 7-8g; a packed one up to 9g. For consistency, always use level scoops. If your coffee scoop didn't come with your machine, it's probably a standard 2-tablespoon size.
Brewing for a crowd means scaling up precisely. **10 people:** Assume 2 cups each = 20 cups of 6 oz = 120 oz water. At standard strength: 200g coffee (~36 tablespoons). A standard drip machine makes 60 oz, so you need 2 full pots. **25 people:** 50 cups = 300 oz. Commercial percolators (100-cup size) handle this in one batch. Use 500g coffee. **Pro tip:** Make it slightly stronger than normal — coffee in a large carafe cools and dilutes slightly from steam condensation.
A tablespoon of light-roast, coarsely ground coffee weighs about 4.5g. A tablespoon of dark-roast, finely ground coffee weighs about 6.5g. That's a 44% difference from the same measuring tool! This is why serious coffee recipes always specify grams. A $10-15 kitchen scale pays for itself by eliminating this inconsistency.

For a 6-oz cup: about 2 level tablespoons (10g) for standard strength. For an 8-oz mug: about 2.5-3 tablespoons. For a large 12-oz mug: about 4 tablespoons. Always level the spoon — heaped tablespoons vary wildly.
A standard 12-cup coffee maker brews 60 oz (5 oz per "cup"). You need about 10-12 scoops (standard 2-tbsp scoops) or 100-130g of coffee for a full pot at standard strength.
Coffee makers use 5 oz per "cup" while a standard US measuring cup is 8 oz. A "12-cup" coffee maker brews 60 oz (7.5 measuring cups). This is an industry convention dating back decades.
Weight (grams) is always more accurate because grind size changes volume. A tablespoon of fine espresso grind weighs more than a tablespoon of coarse French press grind. If you have a kitchen scale, use grams.
Use more coffee (lower ratio) rather than brewing longer or using finer grind. Extra brew time or finer grind over-extracts, creating bitterness. More coffee = stronger but balanced flavor.
Use about 1:5 (75g coffee per 375mL water) for cold brew concentrate. Steep 12-24 hours, then dilute 1:1 with water, milk, or over ice. Undiluted cold brew concentrate is very strong.
