About Converting Cubic Millimeter per Seconds to Cubic Meter per Hours
Cubic Millimeter per Seconds and Cubic Meter per Hours 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 meter per hours = cubic millimeter per seconds × 0.0000036
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per seconds equals 1e-9 base units, and 1 cubic meter per hours equals 0.000277777777778 base units, so dividing one by the other gives the direct cubic millimeter per seconds-to-cubic meter per hours factor of 0.0000036.
Simple example
1 mm3/s × 0.0000036 = 0.0000036 m3/h
1 cubic millimeter per seconds = 0.0000036 cubic meter per hours.
Real-world example
60 mm3/s × 0.0000036 = 0.000216 m3/h
60 cubic millimeter per seconds = 0.000216 cubic meter per hours.

Reverse conversion: Cubic Meter per Hours to Cubic Millimeter per Seconds
0.0000036 m3/h × 277777.7778 = 1 mm3/s
0.0000036 cubic meter per hours = 1 cubic millimeter per seconds.
cubic millimeter per seconds = cubic meter per hours × 277777.777778

Understanding the 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.
Where it's used: Standard flow-rate unit for HVAC and industrial equipment ratings internationally, outside the US
Uses of the Cubic Meter per Hours today
- HVAC equipment airflow and liquid-flow ratings
- Industrial pump and system flow specifications
- Building ventilation system design

Frequently asked questions
How many cubic meter per hours are in 1 cubic millimeter per seconds?
1 cubic millimeter per seconds equals 0.0000036 cubic meter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per seconds to cubic meter per hours?
Multiply the cubic millimeter per seconds value by 0.0000036. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per hours back to cubic millimeter per seconds?
Use the reverse factor: 1 cubic meter per hours equals 277,777.7778 cubic millimeter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per seconds?
Cubic Millimeter per Seconds (mm3/s) is a unit of flow rate.
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.
Is the cubic millimeter per seconds to cubic meter per hours conversion exact?
Yes. Both cubic millimeter per seconds and cubic meter per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.0000036 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.
