How to Convert Imperial Gallons to Millimeters Cube

Example: How many millimeters cube are equivalent to 3.76 imperial gallons?


1 imperial gallons = 4545000 millimeters cube

3.76 imperial gallons = Y millimeters cube

Assuming Y is the answer, and by criss-cross principle;

Y equals 3.76 times 4545000 over 1

(i.e.) Y = 3.76 * 4545000 / 1 = 17089200 millimeters cube

Answer is: 17089200 millimeters cube are equivalent to 3.76 imperial gallons.
