How to Convert Millimeters Cube to US Gallons

Example: How many US gallons are equivalent to 2.47 millimeters cube?


1 millimeters cube = 2.64172176858E-7 US gallons

2.47 millimeters cube = Y US gallons

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

Y equals 2.47 times 2.64172176858E-7 over 1

(i.e.) Y = 2.47 * 2.64172176858E-7 / 1 = 6.52505276839E-7 US gallons

Answer is: 6.52505276839E-7 US gallons are equivalent to 2.47 millimeters cube.
