How to Convert US Gallons to Imperial Gallons
Example: How many imperial gallons are equivalent to 20.43 US gallons?
As;
1 US gallons = 0.832701 imperial gallons
20.43 US gallons = Y imperial gallons
Assuming Y is the answer, and by criss-cross principle;
Y equals 20.43 times 0.832701 over 1
(i.e.) Y = 20.43 * 0.832701 / 1 = 17.01208143 imperial gallons
Answer is: 17.01208143 imperial gallons are equivalent to 20.43 US gallons.
