100 centiliters = 1 liter1.5 * 100 = 150 centileters ■
Well assuming that the 360 is a measurement in centileters, half a litre is 500 centileters. So you would need to add 500 - 360 = 140 extra centileters to make half a litre.
"centi" indicates .01, or 1/100 of whatever unit it is before. So there are 100 centileters in one liter, and a centileter is 1/100th of a liter.
