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.
Stop guessing. Whether you use a scale, tablespoon, or scoop, this calculator gives you the exact amount for your cup size and preferred strength, every time. Keep these notes focused on your operational context. Tie the context to the calculator’s intended domain. Use this clarification to avoid ambiguous interpretation.

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.
