About this conversion
This page converts us gallons per year (gal/yr) into hectoliters per hour (hL/h), two units of volumetric flow rate.
The US Gallon (gal) is a unit of volume. The Year (yr) is a unit of time.
The Hectoliter (hL) is a unit of volume. The Hour (h) is a unit of time.
The formula is hL/h = gal/yr × 4.31838e-6, 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.
