What is a Coffee Brew Calculator?

A coffee brew calculator is an online tool or app that helps you determine the perfect coffee-to-water ratio based on your brewing method, desired coffee strength, and cup size. It simplifies the often confusing process of calculating how much coffee you need for a specific amount of water.

Whether you’re brewing a single cup or an entire pot, this calculator ensures you get a consistent and delicious cup of coffee every time. It’s ideal for coffee enthusiasts who want to achieve barista-quality coffee at home without the guesswork.

Quick Tip: The standard coffee-to-water ratio is 1:15 to 1:18, meaning one gram of coffee for every 15-18 grams of water, but this varies depending on the brew method and personal taste.

Volume Equivalents:

1 Cup (US) = 237 ml (milliliters) = 8 fluid ounces (oz)
1 Tablespoon (tbsp) = 15 ml = 0.5 fluid ounces = 3 teaspoons
1 Teaspoon (tsp) = 5 ml = 0.17 fluid ounces
1 Coffee Scoop = 2 tablespoons (30 ml) = 1 ounce = 6 teaspoons

Coffee-to-Water Ratios (Volume Equivalents):

Drip Coffee:
- 1 cup (237 ml) of water typically requires about 1.5 tablespoons (22.5 ml) of coffee grounds.
- For 1 liter (1000 ml) of water, you need around 7 tablespoons (105 ml) of coffee grounds.
French Press:
- 1 cup (237 ml) of water needs 2 tablespoons (30 ml) of coffee.
- For 1 liter of water, you’d use about 8 tablespoons (120 ml) of coffee.
Espresso:
- A single shot of espresso is 1 oz (30 ml), requiring 7-9 grams of finely ground coffee.
- A double shot uses 2 oz (60 ml) and requires 14-18 grams of coffee.
Pour Over (e.g., Chemex):
- For 1 cup (237 ml) of water, about 1.5 tablespoons (22.5 ml) of coffee is needed.
- For 1 liter of water, use about 7 tablespoons (105 ml) of coffee.
Cold Brew:
- For a 1:8 ratio (for a lighter brew), you’d use 1 cup (237 ml) of coffee grounds with 8 cups (1900 ml) of water.
- For a 1:5 ratio (for a strong concentrate), you’d need 1 cup (237 ml) of coffee grounds with 5 cups (1180 ml) of water.

Weight Equivalents for Coffee Beans (Common Conversions):

1 Tablespoon of Coffee ≈ 5-7 grams (depending on grind size and bean type)
1 Cup of Coffee Beans (whole) ≈ 82-85 grams
1 Coffee Scoop (2 tbsp) ≈ 10-12 grams of coffee

Coffee Grounds to Volume Conversions:

1 tablespoon of coffee grounds ≈ 5-7 grams
1 ounce of coffee grounds ≈ 28 grams

Conversion for Water:

1 liter of water = 1000 ml = 33.8 fluid ounces = ~4.2 US cups
1 cup of water = 237 ml = 8 fluid ounces

General Coffee-to-Water Ratio Recommendations:

1:15 to 1:18 ratio is common for pour-over, French press, and drip coffee. This means for every 1 gram of coffee, you use 15 to 18 grams of water.
For stronger espresso-like brews, a 1:2 ratio is common (1 gram of coffee for 2 grams of water).
