## How to Convert Imperial Gallons to US Gallons

*Example: How many US gallons are equivalent to 77.02 imperial gallons?*

As;

1 imperial gallons = 1.2 US gallons

77.02 imperial gallons = Y US gallons

Y equals 77.02 times 1.2 over 1

(i.e.) Y = 77.02 * 1.2 / 1 = 92.424 US gallons

Answer is: 92.424 US gallons are equivalent to 77.02 imperial gallons.
