About this conversion
This page converts teaspoons per year (tsp/yr) into us gallons per millisecond (gal/ms), two units of volumetric flow rate.
The Teaspoon (tsp) is a unit of volume. The Year (yr) is a unit of time.
The US Gallon (gal) is a unit of volume. The Millisecond (ms) is a unit of time.
The formula is gal/ms = tsp/yr × 4.12614e-14, 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.
