About Converting Metric teaspoon per Hours to Milliliters per Millisecond
Metric teaspoon per Hours and Milliliter 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
milliliters per millisecond = metric teaspoon per hours × 0.00000138888888889
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 millisecond equals 0.001 base units, so dividing one by the other gives the direct metric teaspoon per hours-to-milliliter per millisecond factor of 0.00000138888888889.
Simple example
1 metric tsp/h × 0.000001388888889 = 0.0000013889 mL/ms
1 metric teaspoon per hours = 0.0000013889 milliliters per millisecond.
Real-world example
60 metric tsp/h × 0.000001388888889 = 0.0000833333 mL/ms
60 metric teaspoon per hours = 0.0000833333 milliliters per millisecond.

Frequently asked questions
How many milliliters per millisecond are in 1 metric teaspoon per hours?
1 metric teaspoon per hours equals 0.0000013889 milliliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert metric teaspoon per hours to milliliter per millisecond?
Multiply the metric teaspoon per hours value by 0.000001388888889. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per millisecond back to metric teaspoon per hours?
Use the reverse factor: 1 milliliter per millisecond equals 720,000 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 millisecond?
Milliliter per Millisecond (mL/ms) is a unit of flow rate.
Is the metric teaspoon per hours to milliliter per millisecond conversion exact?
Yes. Both metric teaspoon per hours and milliliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000001388888889 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.
