A bit of history:

> The gō or cup is a traditional Japanese unit based on the ge which is equal to 10 shaku or 1⁄10 shō. Back in the year 1891 it was officially equated with 2401/13310 liters. The gō is the traditional amount used for a serving of rice and a cup of sake in Japanese cuisine. Although the gō is no longer used as an official unit, 1-gō measuring cups or their 180ml metric equivalents are often included with modern premium rice cookers.

> Measuring rice correctly is the key to make delicious rice. For rice measurement, we use a traditional Japanese measure called go or rice cup. A level cup of this measuring cup is 1 rice cup. 1 rice cup equals approximately ¾ US cup or 180 ml.

I had no idea this was the case! Yeesh, that's even worse than I imagined.

Non metric units are a nightmare! I find them terribly interesting, but if you're looking for an unambiguous unit of measure, the metric system is the way.

I'm totally on board. Hard to convince the other 300 megapeople living in this country though :(
