About Converting Metric teaspoon per Hours to Teaspoons per Millisecond
Metric teaspoon per Hours and Teaspoon 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
teaspoons per millisecond = metric teaspoon per hours × 2.817835e-7
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 teaspoon per millisecond equals 0.00492892159375 base units, so dividing one by the other gives the direct metric teaspoon per hours-to-teaspoon per millisecond factor of 2.817835e-7.
Simple example
1 metric tsp/h × 2.817835e-7 = 2.817835e-7 tsp/ms
1 metric teaspoon per hours = 2.817835e-7 teaspoons per millisecond.
Real-world example
60 metric tsp/h × 2.817835e-7 = 0.000016907 tsp/ms
60 metric teaspoon per hours = 0.000016907 teaspoons per millisecond.

Frequently asked questions
How many teaspoons per millisecond are in 1 metric teaspoon per hours?
1 metric teaspoon per hours equals 2.817835e-7 teaspoons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert metric teaspoon per hours to teaspoon per millisecond?
Multiply the metric teaspoon per hours value by 2.817835e-7. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per millisecond back to metric teaspoon per hours?
Use the reverse factor: 1 teaspoon per millisecond equals 3,548,823.547 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 teaspoon per millisecond?
Teaspoon per Millisecond (tsp/ms) is a unit of flow rate.
Is the metric teaspoon per hours to teaspoon per millisecond conversion exact?
Yes. Both metric teaspoon per hours and teaspoon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 2.817835e-7 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.
