About Converting Gallons per Millisecond to Quart per Minutes
Gallon 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 = gallons per millisecond × 240000
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per millisecond equals 3.785411784 base units, and 1 quart per minutes equals 0.0000157725491 base units, so dividing one by the other gives the direct gallon per millisecond-to-quart per minutes factor of 240000.
Simple example
1 gal/ms × 240000 = 240,000 qt/min
1 gallon per millisecond = 240,000 quart per minutes.
Real-world example
60 gal/ms × 240000 = 14,400,000 qt/min
60 gallons per millisecond = 14,400,000 quart per minutes.

Frequently asked questions
How many quart per minutes are in 1 gallon per millisecond?
1 gallon per millisecond equals 240,000 quart per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to quart per minutes?
Multiply the gallon per millisecond value by 240000. The converter above does this instantly to whatever precision you set.
How do I convert quart per minutes back to gallon per millisecond?
Use the reverse factor: 1 quart per minutes equals 0.0000041667 gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per millisecond?
Gallon per Millisecond (gal/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 gallon per millisecond to quart per minutes conversion exact?
Yes. Both gallon per millisecond and quart per minutes are defined by fixed standards rather than physical artifacts, so the factor of 240000 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.
