About this conversion
This page converts us gallons per week (gal/wk) into cubic yards per year (yd3/yr), two units of volumetric flow rate.
The US Gallon (gal) is a unit of volume. The Week (wk) is a unit of time.
The Cubic Yard (yd3) is a unit of volume. The Year (yr) is a unit of time.
The formula is yd3/yr = gal/wk × 0.258338, 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.
