About Converting Cubic Megameters to Oil barrels
Cubic Megameter and Oil barrel appear side by side at fuel pumps and on beverage labels, since the US measures liquids in gallons while most of the world uses liters. Specifically: Cubic metric volume unit, and an oil barrel is 42 US gallons.
Formula
oil barrels = cubic megameters × 6.289811e+18
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic megameter equals 1e+18 base units, and 1 oil barrel equals 0.158987294928 base units, so dividing one by the other gives the direct cubic megameter-to-oil barrel factor of 6.289811e+18.
Simple example
1 Mm3 × 6.289811e+18 = 6.289811e+18 bbl
1 cubic megameter = 6.289811e+18 oil barrels.
Real-world example
10 Mm3 × 6.289811e+18 = 6.289811e+19 bbl
10 cubic megameters = 6.289811e+19 oil barrels.
