About Converting Milliliter per Hours to Milliliter per Seconds
Milliliter per Hours and Milliliter 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
milliliter per seconds = milliliter per hours × 0.000277777777778
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 milliliter per seconds equals 0.000001 base units, so dividing one by the other gives the direct milliliter per hours-to-milliliter per seconds factor of 0.000277777777778.
Simple example
1 mL/h × 0.0002777777778 = 0.0002777778 mL/s
1 milliliter per hours = 0.0002777778 milliliter per seconds.
Real-world example
60 mL/h × 0.0002777777778 = 0.0166666667 mL/s
60 milliliter per hours = 0.0166666667 milliliter per seconds.

Reverse conversion: Milliliter per Seconds to Milliliter per Hours
0.0002777778 mL/s × 3600 = 1.00000008 mL/h
0.0002777778 milliliter per seconds = 1.00000008 milliliter per hours.
milliliter per hours = milliliter per seconds × 3600

Frequently asked questions
How many milliliter per seconds are in 1 milliliter per hours?
1 milliliter per hours equals 0.0002777778 milliliter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per hours to milliliter per seconds?
Multiply the milliliter per hours value by 0.0002777777778. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per seconds back to milliliter per hours?
Use the reverse factor: 1 milliliter per seconds equals 3,600 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 milliliter per seconds?
Milliliter per Seconds (mL/s) is a unit of flow rate.
Is the milliliter per hours to milliliter per seconds conversion exact?
Yes. Both milliliter per hours and milliliter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0002777777778 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.
