About Converting Quart per Seconds to Milliliter per Hours
Quart per Seconds and Milliliter 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
milliliter per hours = quart per seconds × 3406870.6056
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per seconds equals 0.000946352946 base units, and 1 milliliter per hours equals 2.777778e-10 base units, so dividing one by the other gives the direct quart per seconds-to-milliliter per hours factor of 3406870.6056.
Simple example
1 qt/s × 3406870.606 = 3,406,870.606 mL/h
1 quart per seconds = 3,406,870.606 milliliter per hours.
Real-world example
60 qt/s × 3406870.606 = 204,412,236.3 mL/h
60 quart per seconds = 204,412,236.3 milliliter per hours.

Frequently asked questions
How many milliliter per hours are in 1 quart per seconds?
1 quart per seconds equals 3,406,870.606 milliliter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert quart per seconds to milliliter per hours?
Multiply the quart per seconds value by 3406870.606. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per hours back to quart per seconds?
Use the reverse factor: 1 milliliter per hours equals 2.935245e-7 quart per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per seconds?
Quart per Seconds (qt/s) is a unit of flow rate.
What is a milliliter per hours?
Milliliter per Hours (mL/h) is a unit of flow rate.
Is the quart per seconds to milliliter per hours conversion exact?
Yes. Both quart per seconds and milliliter per hours are defined by fixed standards rather than physical artifacts, so the factor of 3406870.606 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.
