About Converting Teaspoon per Days to Cubic inch per Weeks
Teaspoon per Days and Cubic inch per Weeks 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 weeks = teaspoon per days × 2.10546875
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 weeks equals 2.709501e-11 base units, so dividing one by the other gives the direct teaspoon per days-to-cubic inch per weeks factor of 2.10546875.
Simple example
1 tsp/d × 2.10546875 = 2.10546875 in3/wk
1 teaspoon per days = 2.10546875 cubic inch per weeks.
Real-world example
60 tsp/d × 2.10546875 = 126.328125 in3/wk
60 teaspoon per days = 126.328125 cubic inch per weeks.

What is a teaspoon per days?
Teaspoon per Days (tsp/d) is a unit of flow rate.
What is a cubic inch per weeks?
Cubic inch per Weeks (in3/wk) is a unit of flow rate.
Is the teaspoon per days to cubic inch per weeks conversion exact?
Yes. Both teaspoon per days and cubic inch per weeks are defined by fixed standards rather than physical artifacts, so the factor of 2.10546875 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.
