๐ณ Cooking Measurement Converter
Convert between common Japanese cooking measurements โ tablespoon (ๅคงใใ, 15ml), teaspoon (ๅฐใใ, 5ml), cup (ใซใใ, 200ml), and milliliters โ and see the equivalent weight in grams for a selected ingredient. Useful for adjusting recipe quantities or substituting when you don't have the right measuring spoon or cup on hand. Note that the Japanese cup (200ml) differs from the US cup (240ml).
How to use
- Enter an amount and choose a unit (tablespoon, teaspoon, cup, or ml).
- Select an ingredient (water, sugar, flour, etc.) to see its approximate weight in grams.
- Check the converted values in the other measurement units at the same time.
How the calculation works
This tool uses Japanese kitchen measures: a tablespoon of 15 ml, a teaspoon of 5 ml and a cup of 200 ml. The US cup is 240 ml, so take care when working from an American recipe. To turn volume into weight it uses an average density for each ingredient โ grams per millilitre. Water is 1 ml = 1 g; soy sauce about 1 ml = 1.2 g. Weight = volume (ml) ร density, so an ingredient denser than water weighs more than water for the same spoonful. Powders are the exception to trust: whether they were sifted, and how firmly they were packed, changes the weight of the same volume considerably. Treat the weight shown as an estimate based on an average, and for baking where accuracy matters, use kitchen scales.
Worked example
Weight of two tablespoons of soy sauce 1. Volume: 15 ml ร 2 = 30 ml 2. Weight: 30 ร 1.2 = 36 g One cup (200 ml) of flour comes to roughly 200 ร 0.55 = 110 g. The same cup of water weighs 200 g, which shows how far volume and weight diverge for powders. One tablespoon of butter is about 15 ร 0.95 โ 14 g.
Things to be aware of
- The cup here is the Japanese 200 ml cup, not the US 240 ml cup.
- Flour and sugar vary in weight for the same volume depending on packing and on the type of sugar.
- When measuring liquids, set the jug on a level surface and read the scale at eye level.
- Weights are estimates from average densities. Weigh ingredients when precision matters.
FAQ
Is the cup here the same as a US cup?
No. This tool uses the Japanese cooking cup, which is 200ml. The US cup is 240ml, so be careful when following recipes from different countries.
How accurate is the weight conversion?
The weight is estimated using an average density (g/ml) for each ingredient. Actual weight can vary depending on how the ingredient is packed or its temperature, so use it as a helpful approximation.
Can I use this if I don't have measuring spoons?
Yes โ since tablespoon and teaspoon amounts convert to milliliters, any container with ml markings can substitute.
Can it convert soy sauce or miso to grams?
Yes โ density values for several ingredients, including soy sauce and miso, are built in, so you can convert from spoons to grams.
Can I use this to scale a recipe up or down?
Yes โ just change the amount field and both the unit conversion and the weight recalculate, which makes scaling a recipe from 2 to 4 servings easy.
