## How to Convert Imperial Gallons to US Barrels Oil

*Example: How many US barrels oil are equivalent to 47.38 imperial gallons?*

As;

1 imperial gallons = 0.028593 US barrels oil

47.38 imperial gallons = Y US barrels oil

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

Y equals 47.38 times 0.028593 over 1

(i.e.) Y = 47.38 * 0.028593 / 1 = 1.35473634 US barrels oil

Answer is: 1.35473634 US barrels oil are equivalent to 47.38 imperial gallons.
