About Converting Milliliter per Hours to Quart per Seconds
Milliliter per Hours and Quart 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
quart per seconds = milliliter per hours × 2.935245e-7
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 quart per seconds equals 0.000946352946 base units, so dividing one by the other gives the direct milliliter per hours-to-quart per seconds factor of 2.935245e-7.
Simple example
1 mL/h × 2.935245e-7 = 2.935245e-7 qt/s
1 milliliter per hours = 2.935245e-7 quart per seconds.
Real-world example
60 mL/h × 2.935245e-7 = 0.0000176115 qt/s
60 milliliter per hours = 0.0000176115 quart per seconds.

Frequently asked questions
How many quart per seconds are in 1 milliliter per hours?
1 milliliter per hours equals 2.935245e-7 quart per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per hours to quart per seconds?
Multiply the milliliter per hours value by 2.935245e-7. The converter above does this instantly to whatever precision you set.
How do I convert quart per seconds back to milliliter per hours?
Use the reverse factor: 1 quart per seconds equals 3,406,870.606 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 quart per seconds?
Quart per Seconds (qt/s) is a unit of flow rate.
Is the milliliter per hours to quart per seconds conversion exact?
Yes. Both milliliter per hours and quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 2.935245e-7 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.
