About Converting Cubic Meter per Hours to Milliliters per Millisecond
Cubic Meter per Hours and Milliliter 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. Cubic Meter per Hours is most often used for hvac equipment airflow and liquid-flow ratings.
Formula
milliliters per millisecond = cubic meter per hours × 0.277777777778
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per hours equals 0.000277777777778 base units, and 1 milliliter per millisecond equals 0.001 base units, so dividing one by the other gives the direct cubic meter per hours-to-milliliter per millisecond factor of 0.277777777778.
Simple example
1 m3/h × 0.2777777778 = 0.2777777778 mL/ms
1 cubic meter per hours = 0.2777777778 milliliters per millisecond.
Real-world example
60 m3/h × 0.2777777778 = 16.66666667 mL/ms
60 cubic meter per hours = 16.66666667 milliliters per millisecond.
Conversion table

| 1 m3/h | 0.2777777778 mL/ms |
| 10 m3/h | 2.777777778 mL/ms |
| 60 m3/h | 16.66666667 mL/ms |
| 100 m3/h | 27.77777778 mL/ms |
| 1,000 m3/h | 277.7777778 mL/ms |
Reverse conversion: Milliliter per Millisecond to Cubic Meter per Hours
0.2777777778 mL/ms × 3.6 = 1 m3/h
0.2777777778 milliliters per millisecond = 1 cubic meter per hours.
cubic meter per hours = milliliters per millisecond × 3.6

Frequently asked questions
How many milliliters per millisecond are in 1 cubic meter per hours?
1 cubic meter per hours equals 0.2777777778 milliliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per hours to milliliter per millisecond?
Multiply the cubic meter per hours value by 0.2777777778. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per millisecond back to cubic meter per hours?
Use the reverse factor: 1 milliliter per millisecond equals 3.6 cubic meter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per hours?
Cubic Meter per Hours (m3/h) measures volumetric flow rate. One cubic meter of volume passing a point every hour — a common scale for equipment and system flow ratings. It is classified as a metric derived flow-rate unit.
What is a milliliter per millisecond?
Milliliter per Millisecond (mL/ms) is a unit of flow rate.
Is the cubic meter per hours to milliliter per millisecond conversion exact?
Yes. Both cubic meter per hours and milliliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.2777777778 used above is exact to as many digits as you choose to display.
Where is the cubic meter per hours still used today?
Standard flow-rate unit for HVAC and industrial equipment ratings internationally, outside the US
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.
