About Converting Liters per Millisecond to Cubic Millimeter per Hours
Liter per Millisecond 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 = liters per millisecond × 3.6e+12
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per millisecond equals 1 base unit, and 1 cubic millimeter per hours equals 2.777778e-13 base units, so dividing one by the other gives the direct liter per millisecond-to-cubic millimeter per hours factor of 3.6e+12.
Simple example
1 L/ms × 3.6e+12 = 3.6e+12 mm3/h
1 liter per millisecond = 3.6e+12 cubic millimeter per hours.
Real-world example
60 L/ms × 3.6e+12 = 2.16e+14 mm3/h
60 liters per millisecond = 2.16e+14 cubic millimeter per hours.

Reverse conversion: Cubic Millimeter per Hours to Liter per Millisecond
3.6e+12 mm3/h × 2.777778e-13 = 1 L/ms
3.6e+12 cubic millimeter per hours = 1 liter per millisecond.
liters per millisecond = cubic millimeter per hours × 2.777778e-13

Frequently asked questions
How many cubic millimeter per hours are in 1 liter per millisecond?
1 liter per millisecond equals 3.6e+12 cubic millimeter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert liter per millisecond to cubic millimeter per hours?
Multiply the liter per millisecond value by 3.6e+12. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per hours back to liter per millisecond?
Use the reverse factor: 1 cubic millimeter per hours equals 2.777778e-13 liters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per millisecond?
Liter per Millisecond (L/ms) 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 liter per millisecond to cubic millimeter per hours conversion exact?
Yes. Both liter per millisecond and cubic millimeter per hours are defined by fixed standards rather than physical artifacts, so the factor of 3.6e+12 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.
