Matcha calculators
Four things worth working out rather than guessing: how much powder and water to use, how much caffeine that gives you, how long to let the kettle cool, and what you're actually paying per gram. All of them run in the browser — nothing is sent anywhere.
Matcha ratio calculator
How much matcha and water for usucha, koicha, a hot latte or an iced one — in grams, scoops and teaspoons.
2g to 60ml for usucha; 3g for a latte
Matcha caffeine calculator
Caffeine and L-theanine for any dose and grade, with coffee and green tea equivalents.
≈ 60mg caffeine in a 2g bowl
Grams to teaspoons converter
Convert any matcha dose between grams, level and heaped teaspoons, tablespoons and chashaku scoops.
2g ≈ 1¼ level tsp, or 2 chashaku scoops
Matcha latte calorie calculator
Build your drink — milk, size, dose, sweetener — and see the calories split by source.
50–240 kcal; the milk decides nearly all of it
Water cooling calculator
How long boiled water takes to reach 70, 75 or 80°C in a kettle, a cup or a flask.
≈ 5–6 min in an open half-litre kettle
Matcha cost calculator
Price per gram, cost per cup, how long the tin lasts, and what that price band actually buys.
$0.35–0.60/g is the latte-grade sweet spot
The numbers, if you just want them
Standard doses for every preparation. The calculators exist to scale these and to translate between grams, scoops and teaspoons.
| Drink | Matcha | Liquid | Water temp | Scoops |
|---|---|---|---|---|
| Usucha | 2 g | 60 ml water | 75°C | 2 |
| Koicha | 4 g | 30 ml water | 70°C | 4 |
| Hot latte | 3 g | 60 ml water + 180 ml milk | 78°C | 3 |
| Iced latte | 3 g | 60 ml water + 150 ml milk + ice | 78°C | 3 |
Scoops are chashaku scoops at roughly 1g each. A level teaspoon holds about 1.7g and a heaped one up to 2.5g, which is why teaspoon measurements vary so much.
Frequently asked
How much matcha should I use per cup?
2 grams for a bowl of usucha with 60ml of water, 3 grams for a 240ml latte, and 4 grams for koicha with about 30ml of water. The latte dose is higher because milk masks the tea. In traditional terms, a chashaku scoop holds roughly 1 gram.
What temperature should water be for matcha?
70 to 80°C. Use 70°C for koicha, around 75°C for usucha with good ceremonial grade, and up to 80°C for latte or culinary grade. Boiling water extracts catechins aggressively and degrades L-theanine, which produces bitterness that whisking cannot fix.
How much caffeine is in matcha?
Roughly 30mg per gram, so a standard 2g bowl contains about 60mg — a little under a cup of drip coffee at around 95mg. Matcha also contains L-theanine, which moderates how the caffeine is felt, so the same dose tends to feel steadier than coffee.
How much should matcha cost per gram?
Under $0.20 per gram signals bulk culinary quality. $0.35 to $0.60 is premium culinary or latte grade and the value sweet spot for most people. Above $1.20 is ceremonial pricing, which is worth paying if you drink matcha with water alone and largely wasted in a latte.
