About Converting Quart per Minutes to Milliliter per Seconds
Quart per Minutes 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 minutes × 15.7725491
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per minutes equals 0.0000157725491 base units, and 1 milliliter per seconds equals 0.000001 base units, so dividing one by the other gives the direct quart per minutes-to-milliliter per seconds factor of 15.7725491.
Simple example
1 qt/min × 15.7725491 = 15.7725491 mL/s
1 quart per minutes = 15.7725491 milliliter per seconds.
Real-world example
60 qt/min × 15.7725491 = 946.352946 mL/s
60 quart per minutes = 946.352946 milliliter per seconds.

Frequently asked questions
How many milliliter per seconds are in 1 quart per minutes?
1 quart per minutes equals 15.7725491 milliliter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert quart per minutes to milliliter per seconds?
Multiply the quart per minutes value by 15.7725491. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per seconds back to quart per minutes?
Use the reverse factor: 1 milliliter per seconds equals 0.0634012926 quart per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per minutes?
Quart per Minutes (qt/min) 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 minutes to milliliter per seconds conversion exact?
Yes. Both quart per minutes and milliliter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 15.7725491 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.
