About Converting Teaspoon per Days to Cubic inch per Years
Teaspoon per Days 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 days × 109.858095703
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per days equals 5.70477e-11 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 days-to-cubic inch per years factor of 109.858095703.
Simple example
1 tsp/d × 109.8580957 = 109.8580957 in3/yr
1 teaspoon per days = 109.8580957 cubic inch per years.
Real-world example
60 tsp/d × 109.8580957 = 6,591.485742 in3/yr
60 teaspoon per days = 6,591.485742 cubic inch per years.

What is a teaspoon per days?
Teaspoon per Days (tsp/d) 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 days to cubic inch per years conversion exact?
Yes. Both teaspoon per days and cubic inch per years are defined by fixed standards rather than physical artifacts, so the factor of 109.8580957 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.
