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

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