About Converting Milliliter per Hours to Liter per Hours
Milliliter per Hours and Liter 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
liter per hours = milliliter per hours × 0.001
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 liter per hours equals 2.777778e-7 base units, so dividing one by the other gives the direct milliliter per hours-to-liter per hours factor of 0.001.
Simple example
1 mL/h × 0.001 = 0.001 L/h
1 milliliter per hours = 0.001 liter per hours.
Real-world example
60 mL/h × 0.001 = 0.06 L/h
60 milliliter per hours = 0.06 liter per hours.
Conversion table
| Milliliter per Hours (mL/h) | Liter per Hours (L/h) |
|---|---|
| 0.1 mL/h | 0.0001 L/h |
| 1 mL/h | 0.001 L/h |
| 10 mL/h | 0.01 L/h |
| 60 mL/h | 0.06 L/h |
| 100 mL/h | 0.1 L/h |
| 1,000 mL/h | 1 L/h |
Reverse conversion: Liter per Hours to Milliliter per Hours
0.001 L/h × 1000 = 1 mL/h
0.001 liter per hours = 1 milliliter per hours.
milliliter per hours = liter per hours × 1000

Frequently asked questions
How many liter per hours are in 1 milliliter per hours?
1 milliliter per hours equals 0.001 liter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per hours to liter per hours?
Multiply the milliliter per hours value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert liter per hours back to milliliter per hours?
Use the reverse factor: 1 liter per hours equals 1,000 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 liter per hours?
Liter per Hours (L/h) is a unit of flow rate.
Is the milliliter per hours to liter per hours conversion exact?
Yes. Both milliliter per hours and liter per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
