About Converting Liter per Hours to Cubic Millimeters per Millisecond
Liter per Hours and Cubic Millimeter 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. Both are volumetric flow rate units.
Formula
cubic millimeters per millisecond = liter per hours × 0.277777777778
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per hours equals 2.777778e-7 base units, and 1 cubic millimeter per millisecond equals 0.000001 base units, so dividing one by the other gives the direct liter per hours-to-cubic millimeter per millisecond factor of 0.277777777778.
Simple example
1 L/h × 0.2777777778 = 0.2777777778 mm3/ms
1 liter per hours = 0.2777777778 cubic millimeters per millisecond.
Real-world example
60 L/h × 0.2777777778 = 16.66666667 mm3/ms
60 liter per hours = 16.66666667 cubic millimeters per millisecond.
Conversion table
| Liter per Hours (L/h) | Cubic Millimeter per Millisecond (mm3/ms) |
|---|---|

| 1 L/h | 0.2777777778 mm3/ms |
| 10 L/h | 2.777777778 mm3/ms |
| 60 L/h | 16.66666667 mm3/ms |
| 100 L/h | 27.77777778 mm3/ms |
| 1,000 L/h | 277.7777778 mm3/ms |
Reverse conversion: Cubic Millimeter per Millisecond to Liter per Hours
0.2777777778 mm3/ms × 3.6 = 1 L/h
0.2777777778 cubic millimeters per millisecond = 1 liter per hours.
liter per hours = cubic millimeters per millisecond × 3.6

Frequently asked questions
How many cubic millimeters per millisecond are in 1 liter per hours?
1 liter per hours equals 0.2777777778 cubic millimeters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert liter per hours to cubic millimeter per millisecond?
Multiply the liter per hours value by 0.2777777778. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per millisecond back to liter per hours?
Use the reverse factor: 1 cubic millimeter per millisecond equals 3.6 liter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per hours?
Liter per Hours (L/h) is a unit of flow rate.
What is a cubic millimeter per millisecond?
Cubic Millimeter per Millisecond (mm3/ms) is a unit of flow rate.
Is the liter per hours to cubic millimeter per millisecond conversion exact?
Yes. Both liter per hours and cubic millimeter 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.
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.
