About Converting Teaspoon per Years to Cubic inch per Years
Teaspoon per Years and Cubic inch 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
cubic inch per years = teaspoon per years × 0.30078125
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 cubic inch per years equals 5.192854e-13 base units, so dividing one by the other gives the direct teaspoon per years-to-cubic inch per years factor of 0.30078125.
Simple example
1 tsp/yr × 0.30078125 = 0.30078125 in3/yr
1 teaspoon per years = 0.30078125 cubic inch per years.
Real-world example
60 tsp/yr × 0.30078125 = 18.046875 in3/yr
60 teaspoon per years = 18.046875 cubic inch per years.

Multiply the teaspoon per years value by 0.30078125. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per years back to teaspoon per years?
Use the reverse factor: 1 cubic inch per years equals 3.324675325 teaspoon per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per years?
Teaspoon per Years (tsp/yr) is a unit of flow rate.
What is a cubic inch per years?
Cubic inch per Years (in3/yr) is a unit of flow rate.
Is the teaspoon per years to cubic inch per years conversion exact?
Yes. Both teaspoon per years and cubic inch per years are defined by fixed standards rather than physical artifacts, so the factor of 0.30078125 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.
