About Converting Metric teaspoon per Hours to Milliliter per Seconds
Metric 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 = metric teaspoon per hours × 0.00138888888889
This factor comes from each unit's defined relationship to the category's base unit: 1 metric teaspoon per hours equals 1.388889e-9 base units, and 1 milliliter per seconds equals 0.000001 base units, so dividing one by the other gives the direct metric teaspoon per hours-to-milliliter per seconds factor of 0.00138888888889.
Simple example
1 metric tsp/h × 0.001388888889 = 0.0013888889 mL/s
1 metric teaspoon per hours = 0.0013888889 milliliter per seconds.
Real-world example
60 metric tsp/h × 0.001388888889 = 0.0833333333 mL/s
60 metric teaspoon per hours = 0.0833333333 milliliter per seconds.

Frequently asked questions
How many milliliter per seconds are in 1 metric teaspoon per hours?
1 metric teaspoon per hours equals 0.0013888889 milliliter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert metric teaspoon per hours to milliliter per seconds?
Multiply the metric teaspoon per hours value by 0.001388888889. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per seconds back to metric teaspoon per hours?
Use the reverse factor: 1 milliliter per seconds equals 720 metric teaspoon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a metric teaspoon per hours?
Metric teaspoon per Hours (metric 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 metric teaspoon per hours to milliliter per seconds conversion exact?
Yes. Both metric teaspoon per hours and milliliter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.001388888889 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.
