## How to Convert US Barrels Oil to Imperial Gallons

*Example: How many imperial gallons are equivalent to 99.68 US barrels oil?*

As;

1 US barrels oil = 35 imperial gallons

99.68 US barrels oil = Y imperial gallons

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

Y equals 99.68 times 35 over 1

(i.e.) Y = 99.68 * 35 / 1 = 3488.8 imperial gallons

Answer is: 3488.8 imperial gallons are equivalent to 99.68 US barrels oil.
