About Converting Milliliter per Hours to Megaliter per Hours
Milliliter per Hours and Megaliter 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
megaliter per hours = milliliter per hours × 1e-9
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 megaliter per hours equals 0.277777777778 base units, so dividing one by the other gives the direct milliliter per hours-to-megaliter per hours factor of 1e-9.
Simple example
1 mL/h × 1e-9 = 1e-9 ML/h
1 milliliter per hours = 1e-9 megaliter per hours.
Real-world example
60 mL/h × 1e-9 = 6e-8 ML/h
60 milliliter per hours = 6e-8 megaliter per hours.

Frequently asked questions
How many megaliter per hours are in 1 milliliter per hours?
1 milliliter per hours equals 1e-9 megaliter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per hours to megaliter per hours?
Multiply the milliliter per hours value by 1e-9. The converter above does this instantly to whatever precision you set.
How do I convert megaliter per hours back to milliliter per hours?
Use the reverse factor: 1 megaliter per hours equals 1,000,000,000 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 megaliter per hours?
Megaliter per Hours (ML/h) is a unit of flow rate.
Is the milliliter per hours to megaliter per hours conversion exact?
Yes. Both milliliter per hours and megaliter per hours are defined by fixed standards rather than physical artifacts, so the factor of 1e-9 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.
