About Converting Milliliter per Hours to Teaspoon per Seconds
Milliliter per Hours and Teaspoon 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
teaspoon per seconds = milliliter per hours × 0.0000563567045031
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per hours equals 2.777778e-10 base units, and 1 teaspoon per seconds equals 0.00000492892159375 base units, so dividing one by the other gives the direct milliliter per hours-to-teaspoon per seconds factor of 0.0000563567045031.
Simple example
1 mL/h × 0.0000563567045 = 0.0000563567 tsp/s
1 milliliter per hours = 0.0000563567 teaspoon per seconds.
Real-world example
60 mL/h × 0.0000563567045 = 0.0033814023 tsp/s
60 milliliter per hours = 0.0033814023 teaspoon per seconds.

Frequently asked questions
How many teaspoon per seconds are in 1 milliliter per hours?
1 milliliter per hours equals 0.0000563567 teaspoon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per hours to teaspoon per seconds?
Multiply the milliliter per hours value by 0.0000563567045. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per seconds back to milliliter per hours?
Use the reverse factor: 1 teaspoon per seconds equals 17,744.11774 milliliter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per hours?
Milliliter per Hours (mL/h) is a unit of flow rate.
What is a teaspoon per seconds?
Teaspoon per Seconds (tsp/s) is a unit of flow rate.
Is the milliliter per hours to teaspoon per seconds conversion exact?
Yes. Both milliliter per hours and teaspoon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0000563567045 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.
