About Converting Tablespoon per Seconds to Teaspoons per Millisecond
Tablespoon per Seconds 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 = tablespoon per seconds × 0.003
This factor comes from each unit's defined relationship to the category's base unit: 1 tablespoon per seconds equals 0.0000147867647813 base units, and 1 teaspoon per millisecond equals 0.00492892159375 base units, so dividing one by the other gives the direct tablespoon per seconds-to-teaspoon per millisecond factor of 0.003.
Simple example
1 tbsp/s × 0.003 = 0.003 tsp/ms
1 tablespoon per seconds = 0.003 teaspoons per millisecond.
Real-world example
60 tbsp/s × 0.003 = 0.18 tsp/ms
60 tablespoon per seconds = 0.18 teaspoons per millisecond.

Frequently asked questions
How many teaspoons per millisecond are in 1 tablespoon per seconds?
1 tablespoon per seconds equals 0.003 teaspoons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert tablespoon per seconds to teaspoon per millisecond?
Multiply the tablespoon per seconds value by 0.003. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per millisecond back to tablespoon per seconds?
Use the reverse factor: 1 teaspoon per millisecond equals 333.3333333 tablespoon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a tablespoon per seconds?
Tablespoon per Seconds (tbsp/s) 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 tablespoon per seconds to teaspoon per millisecond conversion exact?
Yes. Both tablespoon per seconds and teaspoon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.003 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.
