About Converting Microliter per Hours to Cubic Millimeter per Seconds
Microliter per Hours and Cubic Millimeter per Seconds 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
cubic millimeter per seconds = microliter per hours × 0.000277777777778
This factor comes from each unit's defined relationship to the category's base unit: 1 microliter per hours equals 2.777778e-13 base units, and 1 cubic millimeter per seconds equals 1e-9 base units, so dividing one by the other gives the direct microliter per hours-to-cubic millimeter per seconds factor of 0.000277777777778.
Simple example
1 uL/h × 0.0002777777778 = 0.0002777778 mm3/s
1 microliter per hours = 0.0002777778 cubic millimeter per seconds.
Real-world example
60 uL/h × 0.0002777777778 = 0.0166666667 mm3/s
60 microliter per hours = 0.0166666667 cubic millimeter per seconds.

Frequently asked questions
How many cubic millimeter per seconds are in 1 microliter per hours?
1 microliter per hours equals 0.0002777778 cubic millimeter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert microliter per hours to cubic millimeter per seconds?
Multiply the microliter per hours value by 0.0002777777778. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per seconds back to microliter per hours?
Use the reverse factor: 1 cubic millimeter per seconds equals 3,600 microliter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a microliter per hours?
Microliter per Hours (uL/h) is a unit of flow rate.
What is a cubic millimeter per seconds?
Cubic Millimeter per Seconds (mm3/s) is a unit of flow rate.
Is the microliter per hours to cubic millimeter per seconds conversion exact?
Yes. Both microliter per hours and cubic millimeter per seconds 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.
