About Converting Teaspoon per Seconds to Cubic inches per Fortnight
Teaspoon per Seconds and Cubic inch per Fortnight 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 inches per fortnight = teaspoon per seconds × 363825
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per seconds equals 0.00000492892159375 base units, and 1 cubic inch per fortnight equals 1.354751e-11 base units, so dividing one by the other gives the direct teaspoon per seconds-to-cubic inch per fortnight factor of 363825.
Simple example
1 tsp/s × 363825 = 363,825 in3/fn
1 teaspoon per seconds = 363,825 cubic inches per fortnight.
Real-world example
60 tsp/s × 363825 = 21,829,500 in3/fn
60 teaspoon per seconds = 21,829,500 cubic inches per fortnight.

Frequently asked questions
How many cubic inches per fortnight are in 1 teaspoon per seconds?
1 teaspoon per seconds equals 363,825 cubic inches per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per seconds to cubic inch per fortnight?
Multiply the teaspoon per seconds value by 363825. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per fortnight back to teaspoon per seconds?
Use the reverse factor: 1 cubic inch per fortnight equals 0.0000027486 teaspoon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per seconds?
Teaspoon per Seconds (tsp/s) is a unit of flow rate.
What is a cubic inch per fortnight?
Cubic inch per Fortnight (in3/fn) is a unit of flow rate.
Is the teaspoon per seconds to cubic inch per fortnight conversion exact?
Yes. Both teaspoon per seconds and cubic inch per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 363825 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.
