About Converting Milliliter per Hours to Microliters per Millisecond
Milliliter 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 = milliliter per hours × 0.000277777777778
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per hours equals 2.777778e-10 base units, and 1 microliter per millisecond equals 0.000001 base units, so dividing one by the other gives the direct milliliter per hours-to-microliter per millisecond factor of 0.000277777777778.
Simple example
1 mL/h × 0.0002777777778 = 0.0002777778 uL/ms
1 milliliter per hours = 0.0002777778 microliters per millisecond.
Real-world example
60 mL/h × 0.0002777777778 = 0.0166666667 uL/ms
60 milliliter per hours = 0.0166666667 microliters per millisecond.

Reverse conversion: Microliter per Millisecond to Milliliter per Hours
0.0002777778 uL/ms × 3600 = 1.00000008 mL/h
0.0002777778 microliters per millisecond = 1.00000008 milliliter per hours.
milliliter per hours = microliters per millisecond × 3600

Frequently asked questions
How many microliters per millisecond are in 1 milliliter per hours?
1 milliliter per hours equals 0.0002777778 microliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per hours to microliter per millisecond?
Multiply the milliliter per hours value by 0.0002777777778. The converter above does this instantly to whatever precision you set.
How do I convert microliter per millisecond back to milliliter per hours?
Use the reverse factor: 1 microliter per millisecond equals 3,600 milliliter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per hours?
Milliliter per Hours (mL/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 milliliter per hours to microliter per millisecond conversion exact?
Yes. Both milliliter per hours and microliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.0002777777778 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.
