About Converting Gallon per Months to Quarts per Millisecond
Gallon per Months and Quart per Millisecond 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
quarts per millisecond = gallon per months × 1.521059e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per months equals 1.439459e-9 base units, and 1 quart per millisecond equals 0.946352946 base units, so dividing one by the other gives the direct gallon per months-to-quart per millisecond factor of 1.521059e-9.
Simple example
1 gal/mo × 1.521059e-9 = 1.521059e-9 qt/ms
1 gallon per months = 1.521059e-9 quarts per millisecond.
Real-world example
60 gal/mo × 1.521059e-9 = 9.126357e-8 qt/ms
60 gallon per months = 9.126357e-8 quarts per millisecond.

Frequently asked questions
How many quarts per millisecond are in 1 gallon per months?
1 gallon per months equals 1.521059e-9 quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per months to quart per millisecond?
Multiply the gallon per months value by 1.521059e-9. The converter above does this instantly to whatever precision you set.
How do I convert quart per millisecond back to gallon per months?
Use the reverse factor: 1 quart per millisecond equals 657,436,500 gallon per months. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per months?
Gallon per Months (gal/mo) is a unit of flow rate.
What is a quart per millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
Is the gallon per months to quart per millisecond conversion exact?
Yes. Both gallon per months and quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.521059e-9 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.
