Japanese Cups to Millilitres Converter

Enter a value in Japanese cups (200 mL) to convert it to millilitres and US cups.

How it is calculated

The conversion is a single multiplication. Millilitres = cups × 200, so the tool treats one Japanese cup as exactly 200 mL, the size of the metric measuring cup used in Japanese recipes. US cups = cups × 0.845351, which is 200 divided by 236.588 mL (the US customary cup). The mL result is rounded to two decimals and the US cup result to four. Fractions are fine (1.5 cups is 300 mL). The traditional gō unit is a different, smaller size (180.39 mL), so if your recipe or rice-cooker cup is the old gō, multiply by 180.39 yourself rather than using this figure.

Worked example

A Japanese recipe calls for 3 cups of water. Millilitres: 3 × 200 = 600.00 mL. US cups: 3 × 0.845351 = 2.5361 cups, so the same volume is about two and a half US cups, a little short of three. If you measured with three US cups you would add roughly 110 mL too much (3 × 236.588 = 709.8 mL).

Common mistakes

  • Treating a Japanese cup as a US cup. A US cup is about 18% larger (236.588 mL against 200 mL), which throws off rice-to-water ratios.
  • Mixing up the 200 mL measuring cup with the rice-cooker cup, which follows the traditional gō and is smaller (180.39 mL). Check which cup the recipe means before converting.
  • Reading the second result, labelled in US cups, as a Japanese cup count. It is the same volume expressed in US cups.
  • Typing a recipe fraction such as 3/4 or 1 1/2 into the field. Only plain decimal numbers are read, so enter 0.75 or 1.5; a fraction gives no result.

About this calculator

This converter treats one Japanese cup as 200 mL — the metric cup used in Japanese recipes — and also shows US cups (about 0.845 per Japanese cup). It is not the traditional gō (合), about 180.39 mL, the size on a Japanese rice cooker’s measuring cup; to convert gō to millilitres, multiply by 180.39 yourself.

Home cooks following Japanese recipes for rice, sake serving measures, or traditional dishes need to convert cup readings to millilitres (or to the US cup) when using Western measuring tools, since substituting a standard 236.588 mL US cup throws off rice-to-water ratios.

    A millilitre figure says how much space an ingredient takes, not how much it weighs. Water is close to one gram per millilitre, so 200 mL of water is about 200 g, but flour, sugar or rice weigh quite differently per cup. For baking, look for the recipe's gram amounts if it gives them. Which kinds of recipes do you convert most, rice dishes, soups or baking?
