About Converting Teaspoon per Hours to Milliliter per Seconds
Teaspoon per Hours and Milliliter per Seconds 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
milliliter per seconds = teaspoon per hours × 0.00136914488715
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 milliliter per seconds equals 0.000001 base units, so dividing one by the other gives the direct teaspoon per hours-to-milliliter per seconds factor of 0.00136914488715.
Simple example
1 tsp/h × 0.001369144887 = 0.0013691449 mL/s
1 teaspoon per hours = 0.0013691449 milliliter per seconds.
Real-world example
60 tsp/h × 0.001369144887 = 0.0821486932 mL/s
60 teaspoon per hours = 0.0821486932 milliliter per seconds.

Frequently asked questions
How many milliliter per seconds are in 1 teaspoon per hours?
1 teaspoon per hours equals 0.0013691449 milliliter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per hours to milliliter per seconds?
Multiply the teaspoon per hours value by 0.001369144887. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per seconds back to teaspoon per hours?
Use the reverse factor: 1 milliliter per seconds equals 730.3828904 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 milliliter per seconds?
Milliliter per Seconds (mL/s) is a unit of flow rate.
Is the teaspoon per hours to milliliter per seconds conversion exact?
Yes. Both teaspoon per hours and milliliter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.001369144887 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.
