About Converting Teaspoon per Years to Gallon per Minutes
Teaspoon per Years and Gallon per Minutes both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Both are volumetric flow rate units.
Formula
gallon per minutes = teaspoon per years × 2.475683e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per years equals 1.561913e-13 base units, and 1 gallon per minutes equals 0.0000630901964 base units, so dividing one by the other gives the direct teaspoon per years-to-gallon per minutes factor of 2.475683e-9.
Simple example
1 tsp/yr × 2.475683e-9 = 2.475683e-9 gal/min
1 teaspoon per years = 2.475683e-9 gallon per minutes.
Real-world example
60 tsp/yr × 2.475683e-9 = 1.48541e-7 gal/min
60 teaspoon per years = 1.48541e-7 gallon per minutes.

What is a teaspoon per years?
Teaspoon per Years (tsp/yr) is a unit of flow rate.
What is a gallon per minutes?
Gallon per Minutes (gal/min) measures volumetric flow rate. The standard US unit for pump, plumbing, and irrigation flow-rate specifications. It is classified as a US customary flow-rate unit.
Is the teaspoon per years to gallon per minutes conversion exact?
Yes. Both teaspoon per years and gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 2.475683e-9 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
