About Converting Teaspoon per Hours to Cubic inch per Years
Teaspoon per Hours 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 hours × 2636.59429688
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per hours equals 1.369145e-9 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 hours-to-cubic inch per years factor of 2636.59429688.
Simple example
1 tsp/h × 2636.594297 = 2,636.594297 in3/yr
1 teaspoon per hours = 2,636.594297 cubic inch per years.
Real-world example
60 tsp/h × 2636.594297 = 158,195.6578 in3/yr
60 teaspoon per hours = 158,195.6578 cubic inch per years.

What is a teaspoon per hours?
Teaspoon per Hours (tsp/h) 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 hours to cubic inch per years conversion exact?
Yes. Both teaspoon per hours and cubic inch per years are defined by fixed standards rather than physical artifacts, so the factor of 2636.594297 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.
