## How to Convert US Barrels Oil to Millimeters Cube

*Example: How many millimeters cube are equivalent to 29.78 US barrels oil?*

As;

1 US barrels oil = 158970000 millimeters cube

29.78 US barrels oil = Y millimeters cube

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

Y equals 29.78 times 158970000 over 1

(i.e.) Y = 29.78 * 158970000 / 1 = 4734126600 millimeters cube

Answer is: 4734126600 millimeters cube are equivalent to 29.78 US barrels oil.
