About Converting Quart per Hours to Milliliter per Seconds
Quart 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 = quart per hours × 0.262875818333
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per hours equals 2.628758e-7 base units, and 1 milliliter per seconds equals 0.000001 base units, so dividing one by the other gives the direct quart per hours-to-milliliter per seconds factor of 0.262875818333.
Simple example
1 qt/h × 0.2628758183 = 0.2628758183 mL/s
1 quart per hours = 0.2628758183 milliliter per seconds.
Real-world example
60 qt/h × 0.2628758183 = 15.7725491 mL/s
60 quart per hours = 15.7725491 milliliter per seconds.

Frequently asked questions
How many milliliter per seconds are in 1 quart per hours?
1 quart per hours equals 0.2628758183 milliliter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert quart per hours to milliliter per seconds?
Multiply the quart per hours value by 0.2628758183. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per seconds back to quart per hours?
Use the reverse factor: 1 milliliter per seconds equals 3.804077554 quart per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per hours?
Quart per Hours (qt/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 quart per hours to milliliter per seconds conversion exact?
Yes. Both quart per hours and milliliter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.2628758183 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.
