how big is a grain of rice?
2006-10-20 02:33:21 · update #1
tho you didn't mention the type of rice (variety) nor if it is boiled or not (boiling makes it swell)... can tell you that
as far as i know a grain of rice is bigger than a square millimeter.
about 3 millimeters in length and 1.5 in width...
so... i guess 1/4.5 meaning
0,22222222222222222222222222222222
