About Converting Teaspoon per Seconds to Microliters per Millisecond
Teaspoon per Seconds and Microliter 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
microliters per millisecond = teaspoon per seconds × 4.92892159375
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 microliter per millisecond equals 0.000001 base units, so dividing one by the other gives the direct teaspoon per seconds-to-microliter per millisecond factor of 4.92892159375.
Simple example
1 tsp/s × 4.928921594 = 4.928921594 uL/ms
1 teaspoon per seconds = 4.928921594 microliters per millisecond.
Real-world example
60 tsp/s × 4.928921594 = 295.7352956 uL/ms
60 teaspoon per seconds = 295.7352956 microliters per millisecond.

Frequently asked questions
How many microliters per millisecond are in 1 teaspoon per seconds?
1 teaspoon per seconds equals 4.928921594 microliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per seconds to microliter per millisecond?
Multiply the teaspoon per seconds value by 4.928921594. The converter above does this instantly to whatever precision you set.
How do I convert microliter per millisecond back to teaspoon per seconds?
Use the reverse factor: 1 microliter per millisecond equals 0.2028841362 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 microliter per millisecond?
Microliter per Millisecond (uL/ms) is a unit of flow rate.
Is the teaspoon per seconds to microliter per millisecond conversion exact?
Yes. Both teaspoon per seconds and microliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 4.928921594 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.
