FAQ
Does it handle heights written as feet and inches?
Both feet and inches appear in the length table, so enter 5 foot 10 as 70 inches. There is no combined feet-and-inches input field. One foot is twelve inches.
How many millilitres is "one cup"?
It depends on the country: 200 mL in Japan, about 236.6 mL in the US, about 284 mL in the UK. Mixing a Japanese recipe with a foreign one drifts by nearly 20%, so convert to millilitres in the volume table first. Japan's "1 go" is 180 mL and is a different measure again from the rice cup.
Can it convert currency?
No. Exchange rates change constantly and would have to be fetched from somewhere, and this tool is built not to talk to anything. Unit conversions are fixed physical ratios, so they can be exact without any network access.
Are the values I enter stored?
No, and nothing is sent. The arithmetic happens entirely in the page.
