## How to Convert US Gallons to Imperial Gallons

*Example: How many imperial gallons are equivalent to 14.65 US gallons?*

As;

1 US gallons = 0.832701 imperial gallons

14.65 US gallons = Y imperial gallons

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

Y equals 14.65 times 0.832701 over 1

(i.e.) Y = 14.65 * 0.832701 / 1 = 12.19906965 imperial gallons

Answer is: 12.19906965 imperial gallons are equivalent to 14.65 US gallons.
