About this conversion
This page converts imperial gallons per day (imp gal/d) into cubic feet per year (ft3/yr), two units of volumetric flow rate.
The Imperial Gallon (imp gal) is a unit of volume. The Day (d) is a unit of time.
The Cubic Foot (ft3) is a unit of volume. The Year (yr) is a unit of time.
The formula is ft3/yr = imp gal/d × 58.6374, 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.
