About Converting Microliter per Seconds to Teaspoons per Millisecond
Microliter 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 = microliter per seconds × 2.028841e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 microliter per seconds equals 1e-9 base units, and 1 teaspoon per millisecond equals 0.00492892159375 base units, so dividing one by the other gives the direct microliter per seconds-to-teaspoon per millisecond factor of 2.028841e-7.
Simple example
1 uL/s × 2.028841e-7 = 2.028841e-7 tsp/ms
1 microliter per seconds = 2.028841e-7 teaspoons per millisecond.
Real-world example
60 uL/s × 2.028841e-7 = 0.000012173 tsp/ms
60 microliter per seconds = 0.000012173 teaspoons per millisecond.

Frequently asked questions
How many teaspoons per millisecond are in 1 microliter per seconds?
1 microliter per seconds equals 2.028841e-7 teaspoons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert microliter per seconds to teaspoon per millisecond?
Multiply the microliter per seconds value by 2.028841e-7. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per millisecond back to microliter per seconds?
Use the reverse factor: 1 teaspoon per millisecond equals 4,928,921.594 microliter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a microliter per seconds?
Microliter per Seconds (uL/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 microliter per seconds to teaspoon per millisecond conversion exact?
Yes. Both microliter per seconds and teaspoon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 2.028841e-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.
