How it works

Example
For 500 ml of water at 1:16, use 31.25 g of coffee.

Common questions
- What coffee ratio should I start with?
- Filter coffee commonly starts near 1:15 to 1:17, but roast, grind, method, and preference matter more than a universal number.
- Is one millilitre of water one gram?
- For everyday coffee calculations, one millilitre of water is close enough to one gram.
