Coffee to Water Ratio Calculator for Single Cup Pour Over (1:16 Ratio)
A common pour-over setup using 20g of coffee with a 1:16 ratio for a balanced single mug.
Calculate the required amount of water based on coffee grounds and desired brew ratio. Enter your Coffee Grounds (grams), Brew Ratio (Water-to-Coffee) to get an instant required water (grams). Formula: coffee_grounds * brew_ratio.

How It Works
How It Works
This calculator determines how much water you need based on the amount of coffee grounds you’re using and your preferred brew ratio. The brew ratio tells you how many grams of water are used for every 1 gram of coffee.
To calculate the required water, the calculator multiplies the coffee grounds (in grams) by the brew ratio. The result is the total grams of water needed for your brew.
- Enter the amount of coffee grounds in grams.
- Enter your desired brew ratio (example: 15 for a 1:15 ratio).
- The calculator multiplies coffee grounds by the brew ratio.
- The result is the total water needed in grams.
Understanding the Results
The result shows the exact amount of water (in grams) required to match your chosen coffee-to-water ratio. This helps you brew consistently and control the strength of your coffee.
A lower ratio (like 1:14) makes stronger coffee, while a higher ratio (like 1:17) makes it lighter. Adjust the ratio to match your taste preference.
- The output is the total grams of water to use.
- Lower ratios create stronger coffee.
- Higher ratios create milder coffee.
- Use the same ratio each time for consistent flavor.
Frequently Asked Questions
How does the Coffee to Water Ratio Calculator work?
This calculator multiplies the amount of coffee grounds (in grams) by your chosen brew ratio to determine the required water in grams. For example, if you use 20 grams of coffee with a 1:15 ratio, the calculator multiplies 20 × 15 to give you 300 grams of water. It uses a simple mathematical formula to provide an accurate result.
What does a 1:15 brew ratio mean?
A 1:15 ratio means 1 part coffee to 15 parts water by weight. So for every gram of coffee, you use 15 grams of water. This ratio is commonly used for balanced drip coffee and pour-over brewing methods.
When should I use a different brew ratio?
Different brew methods and taste preferences require different ratios. For example, a stronger cup might use a 1:14 ratio, while a lighter brew might use 1:16 or 1:17. Adjust the ratio based on your flavor preference and brewing method.
Why is the result measured in grams instead of milliliters?
Measuring water in grams ensures greater accuracy, especially for precision brewing. Since 1 gram of water is approximately equal to 1 milliliter, the values are nearly the same. Using weight helps maintain consistency in your brewing process.
Can I use this calculator for espresso?
Espresso typically uses a much lower brew ratio, such as 1:2 or 1:3. While the calculator will still work mathematically, espresso ratios are based on beverage yield rather than total water used. For espresso, make sure you understand your machine's extraction process.
What happens if I enter decimal values?
You can enter decimal values for both coffee grounds and brew ratio for more precise calculations. For example, 18.5 grams of coffee at a 1:15.5 ratio will still calculate correctly. The formula simply multiplies the two numbers to give the required water amount.
