About Converting Gallon per Months to Imperial quarts per Millisecond
Gallon per Months and Imperial 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
imperial quarts per millisecond = gallon per months × 1.266547e-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 imperial quart per millisecond equals 1.1365225 base units, so dividing one by the other gives the direct gallon per months-to-imperial quart per millisecond factor of 1.266547e-9.
Simple example
1 gal/mo × 1.266547e-9 = 1.266547e-9 imp qt/ms
1 gallon per months = 1.266547e-9 imperial quarts per millisecond.
Real-world example
60 gal/mo × 1.266547e-9 = 7.599282e-8 imp qt/ms
60 gallon per months = 7.599282e-8 imperial quarts per millisecond.

Frequently asked questions
How many imperial quarts per millisecond are in 1 gallon per months?
1 gallon per months equals 1.266547e-9 imperial quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per months to imperial quart per millisecond?
Multiply the gallon per months value by 1.266547e-9. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per millisecond back to gallon per months?
Use the reverse factor: 1 imperial quart per millisecond equals 789,548,315.7 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 imperial quart per millisecond?
Imperial quart per Millisecond (imp qt/ms) is a unit of flow rate.
Is the gallon per months to imperial quart per millisecond conversion exact?
Yes. Both gallon per months and imperial quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.266547e-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.
