About Converting Gallon per Weeks to Teaspoon per Years
Gallon per Weeks and Teaspoon per Years 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
teaspoon per years = gallon per weeks × 40072.32
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per weeks equals 6.258948e-9 base units, and 1 teaspoon per years equals 1.561913e-13 base units, so dividing one by the other gives the direct gallon per weeks-to-teaspoon per years factor of 40072.32.
Simple example
1 gal/wk × 40072.32 = 40,072.32 tsp/yr
1 gallon per weeks = 40,072.32 teaspoon per years.
Real-world example
60 gal/wk × 40072.32 = 2,404,339.2 tsp/yr
60 gallon per weeks = 2,404,339.2 teaspoon per years.

How do I convert teaspoon per years back to gallon per weeks?
Use the reverse factor: 1 teaspoon per years equals 0.0000249549 gallon per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per weeks?
Gallon per Weeks (gal/wk) is a unit of flow rate.
What is a teaspoon per years?
Teaspoon per Years (tsp/yr) is a unit of flow rate.
Is the gallon per weeks to teaspoon per years conversion exact?
Yes. Both gallon per weeks and teaspoon per years are defined by fixed standards rather than physical artifacts, so the factor of 40072.32 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.
