About this conversion
This page converts us gallons per hour (gal/h) into megaliters per year (ML/yr), two units of volumetric flow rate.
The US Gallon (gal) is a unit of volume. The Hour (h) is a unit of time.
The Megaliter (ML) is a unit of volume. The Year (yr) is a unit of time.
The formula is ML/yr = gal/h × 0.0331822, 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.
