About Converting Teaspoon per Hours to Cubic Kilometers per Millisecond
Teaspoon per Hours and Cubic Kilometer per Millisecond 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 kilometers per millisecond = teaspoon per hours × 1.369145e-21
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 kilometer per millisecond equals 1e+12 base units, so dividing one by the other gives the direct teaspoon per hours-to-cubic kilometer per millisecond factor of 1.369145e-21.
Simple example
1 tsp/h × 1.369145e-21 = 1.369145e-21 km3/ms
1 teaspoon per hours = 1.369145e-21 cubic kilometers per millisecond.
Real-world example
60 tsp/h × 1.369145e-21 = 8.214869e-20 km3/ms
60 teaspoon per hours = 8.214869e-20 cubic kilometers per millisecond.

Frequently asked questions
How many cubic kilometers per millisecond are in 1 teaspoon per hours?
1 teaspoon per hours equals 1.369145e-21 cubic kilometers per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per hours to cubic kilometer per millisecond?
Multiply the teaspoon per hours value by 1.369145e-21. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per millisecond back to teaspoon per hours?
Use the reverse factor: 1 cubic kilometer per millisecond equals 7.303829e+20 teaspoon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per hours?
Teaspoon per Hours (tsp/h) is a unit of flow rate.
What is a cubic kilometer per millisecond?
Cubic Kilometer per Millisecond (km3/ms) is a unit of flow rate.
Is the teaspoon per hours to cubic kilometer per millisecond conversion exact?
Yes. Both teaspoon per hours and cubic kilometer per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.369145e-21 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.
