About Converting Oil barrels to Cubic Exameters
Oil barrel and Cubic Exameter 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: An oil barrel is 42 US gallons, and cubic metric volume unit.
Formula
cubic exameters = oil barrels × 1.589873e-55
This factor comes from each unit's defined relationship to the category's base unit: 1 oil barrel equals 0.158987294928 base units, and 1 cubic exameter equals 1e+54 base units, so dividing one by the other gives the direct oil barrel-to-cubic exameter factor of 1.589873e-55.
Simple example
1 bbl × 1.589873e-55 = 1.589873e-55 Em3
1 oil barrel = 1.589873e-55 cubic exameters.
Real-world example
10 bbl × 1.589873e-55 = 1.589873e-54 Em3
10 oil barrels = 1.589873e-54 cubic exameters.
