How much coffee grounds per cup?

A good ratio is about 60 g of coffee per litre of water. For a 200 ml cup that is about 12 g, just under two tablespoons. The calculator works out the exact amount based on the strength.

What is the right coffee-to-water ratio?

The golden ratio is about 1:16–1:18 (coffee:water). That means 60 g of coffee per litre of water. For stronger coffee use 1:15, for milder 1:18.

How many grams is one coffee scoop?

A level tablespoon of ground coffee weighs about 7 g, a heaped one about 10–12 g. The scoop that comes with a coffee pack is often about 7 g.

How do I make stronger coffee?

Increase the amount of coffee grounds, do not brew longer — over-brewing makes the coffee bitter. The calculator's "Strong" setting uses 70 g/litre.

How the calculator works and what it’s for▾

How the ratio is calculated

The calculator starts from a solid baseline of about 60 g of coffee per litre of water, which is a ratio of roughly 1:17. From there it scales the amount to the number of cups and the strength you want.

One heaped tablespoon of ground coffee is about 7 g, which helps you measure without a scale.

What you enter and what you get

Enter the number of cups, the cup size in millilitres and the strength you prefer. The calculator shows the total water, the coffee in grams, the number of tablespoons and the final water-to-coffee ratio.

This lets you measure the right amount whether you're brewing a single cup or a full pot.

Adjust to your taste

A 1:17 ratio is a good starting point, but adjust it to your own taste: less water gives a stronger cup and more water a milder one. Grind size and brewing method also affect the flavour.

Fresh, just-ground coffee and the right water temperature noticeably improve the result.

Who it's for

The tool is useful both for your morning brew and when serving guests, when you want a consistent result and the right ratio without guesswork. Different brewing methods call for slightly different ratios — use the calculator as a base and fine-tune.
