About Converting Milliliter per Hours to Cubic Millimeter per Seconds
Milliliter 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 = milliliter per hours × 0.277777777778
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per hours equals 2.777778e-10 base units, and 1 cubic millimeter per seconds equals 1e-9 base units, so dividing one by the other gives the direct milliliter per hours-to-cubic millimeter per seconds factor of 0.277777777778.
Simple example
1 mL/h × 0.2777777778 = 0.2777777778 mm3/s
1 milliliter per hours = 0.2777777778 cubic millimeter per seconds.
Real-world example
60 mL/h × 0.2777777778 = 16.66666667 mm3/s
60 milliliter per hours = 16.66666667 cubic millimeter per seconds.
Conversion table
| Milliliter per Hours (mL/h) | Cubic Millimeter per Seconds (mm3/s) |
|---|---|

| 1 mL/h | 0.2777777778 mm3/s |
| 10 mL/h | 2.777777778 mm3/s |
| 60 mL/h | 16.66666667 mm3/s |
| 100 mL/h | 27.77777778 mm3/s |
| 1,000 mL/h | 277.7777778 mm3/s |
Reverse conversion: Cubic Millimeter per Seconds to Milliliter per Hours
0.2777777778 mm3/s × 3.6 = 1 mL/h
0.2777777778 cubic millimeter per seconds = 1 milliliter per hours.
milliliter per hours = cubic millimeter per seconds × 3.6

Frequently asked questions
How many cubic millimeter per seconds are in 1 milliliter per hours?
1 milliliter per hours equals 0.2777777778 cubic millimeter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per hours to cubic millimeter per seconds?
Multiply the milliliter per hours value by 0.2777777778. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per seconds back to milliliter per hours?
Use the reverse factor: 1 cubic millimeter per seconds equals 3.6 milliliter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per hours?
Milliliter per Hours (mL/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 milliliter per hours to cubic millimeter per seconds conversion exact?
Yes. Both milliliter per hours and cubic millimeter per seconds 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.
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.
