About Converting Liters per Millisecond to Quart per Minutes
Liter per Millisecond and Quart per Minutes 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 minutes = liters per millisecond × 63401.292566
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per millisecond equals 1 base unit, and 1 quart per minutes equals 0.0000157725491 base units, so dividing one by the other gives the direct liter per millisecond-to-quart per minutes factor of 63401.292566.
Simple example
1 L/ms × 63401.29257 = 63,401.29257 qt/min
1 liter per millisecond = 63,401.29257 quart per minutes.
Real-world example
60 L/ms × 63401.29257 = 3,804,077.554 qt/min
60 liters per millisecond = 3,804,077.554 quart per minutes.

Frequently asked questions
How many quart per minutes are in 1 liter per millisecond?
1 liter per millisecond equals 63,401.29257 quart per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert liter per millisecond to quart per minutes?
Multiply the liter per millisecond value by 63401.29257. The converter above does this instantly to whatever precision you set.
How do I convert quart per minutes back to liter per millisecond?
Use the reverse factor: 1 quart per minutes equals 0.0000157725 liters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per millisecond?
Liter per Millisecond (L/ms) is a unit of flow rate.
What is a quart per minutes?
Quart per Minutes (qt/min) is a unit of flow rate.
Is the liter per millisecond to quart per minutes conversion exact?
Yes. Both liter per millisecond and quart per minutes are defined by fixed standards rather than physical artifacts, so the factor of 63401.29257 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.
