About Converting Metric teaspoon per Hours to Microliters per Millisecond
Metric teaspoon per Hours 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 = metric teaspoon per hours × 0.00138888888889
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 microliter per millisecond equals 0.000001 base units, so dividing one by the other gives the direct metric teaspoon per hours-to-microliter per millisecond factor of 0.00138888888889.
Simple example
1 metric tsp/h × 0.001388888889 = 0.0013888889 uL/ms
1 metric teaspoon per hours = 0.0013888889 microliters per millisecond.
Real-world example
60 metric tsp/h × 0.001388888889 = 0.0833333333 uL/ms
60 metric teaspoon per hours = 0.0833333333 microliters per millisecond.

Frequently asked questions
How many microliters per millisecond are in 1 metric teaspoon per hours?
1 metric teaspoon per hours equals 0.0013888889 microliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert metric teaspoon per hours to microliter per millisecond?
Multiply the metric teaspoon per hours value by 0.001388888889. The converter above does this instantly to whatever precision you set.
How do I convert microliter per millisecond back to metric teaspoon per hours?
Use the reverse factor: 1 microliter per millisecond equals 720 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 microliter per millisecond?
Microliter per Millisecond (uL/ms) is a unit of flow rate.
Is the metric teaspoon per hours to microliter per millisecond conversion exact?
Yes. Both metric teaspoon per hours and microliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.001388888889 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.
