About this conversion
This page converts oil barrels per day (bbl/d) into imperial gallons per year (imp gal/yr), two units of volumetric flow rate.
The Oil Barrel (bbl) is a unit of volume. The Day (d) is a unit of time.
The Imperial Gallon (imp gal) is a unit of volume. The Year (yr) is a unit of time.
The formula is imp gal/yr = bbl/d × 12773.4, based on the fixed relationship between these two flow rate units.
Flow rate is calculated as a volume unit divided by a time unit, so every combination of a volume unit and a time unit forms a valid, exact flow rate unit.
