About Converting Teaspoon per Seconds to Milliliters per Millisecond
Teaspoon per Seconds 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 = teaspoon per seconds × 0.00492892159375
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per seconds equals 0.00000492892159375 base units, and 1 milliliter per millisecond equals 0.001 base units, so dividing one by the other gives the direct teaspoon per seconds-to-milliliter per millisecond factor of 0.00492892159375.
Simple example
1 tsp/s × 0.004928921594 = 0.0049289216 mL/ms
1 teaspoon per seconds = 0.0049289216 milliliters per millisecond.
Real-world example
60 tsp/s × 0.004928921594 = 0.2957352956 mL/ms
60 teaspoon per seconds = 0.2957352956 milliliters per millisecond.

Frequently asked questions
How many milliliters per millisecond are in 1 teaspoon per seconds?
1 teaspoon per seconds equals 0.0049289216 milliliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per seconds to milliliter per millisecond?
Multiply the teaspoon per seconds value by 0.004928921594. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per millisecond back to teaspoon per seconds?
Use the reverse factor: 1 milliliter per millisecond equals 202.8841362 teaspoon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per seconds?
Teaspoon per Seconds (tsp/s) 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 teaspoon per seconds to milliliter per millisecond conversion exact?
Yes. Both teaspoon per seconds and milliliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.004928921594 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.
