About Converting Cubic Millimeter per Seconds to Cubic Millimeter per Hours
Cubic Millimeter per Seconds and Cubic Millimeter 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 millimeter per hours = cubic millimeter per seconds × 3600
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 millimeter per hours equals 2.777778e-13 base units, so dividing one by the other gives the direct cubic millimeter per seconds-to-cubic millimeter per hours factor of 3600.
Simple example
1 mm3/s × 3600 = 3,600 mm3/h
1 cubic millimeter per seconds = 3,600 cubic millimeter per hours.
Real-world example
60 mm3/s × 3600 = 216,000 mm3/h
60 cubic millimeter per seconds = 216,000 cubic millimeter per hours.

Frequently asked questions
How many cubic millimeter per hours are in 1 cubic millimeter per seconds?
1 cubic millimeter per seconds equals 3,600 cubic millimeter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per seconds to cubic millimeter per hours?
Multiply the cubic millimeter per seconds value by 3600. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per hours back to cubic millimeter per seconds?
Use the reverse factor: 1 cubic millimeter per hours equals 0.0002777778 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 millimeter per hours?
Cubic Millimeter per Hours (mm3/h) is a unit of flow rate.
Is the cubic millimeter per seconds to cubic millimeter per hours conversion exact?
Yes. Both cubic millimeter per seconds and cubic millimeter per hours are defined by fixed standards rather than physical artifacts, so the factor of 3600 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.
