About Converting Gallon per Seconds to Imperial quart per Hours
Gallon per Seconds and Imperial quart per Hours 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 quart per hours = gallon per seconds × 11990.5082587
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 imperial quart per hours equals 3.157007e-7 base units, so dividing one by the other gives the direct gallon per seconds-to-imperial quart per hours factor of 11990.5082587.
Simple example
1 gal/s × 11990.50826 = 11,990.50826 imp qt/h
1 gallon per seconds = 11,990.50826 imperial quart per hours.
Real-world example
60 gal/s × 11990.50826 = 719,430.4955 imp qt/h
60 gallon per seconds = 719,430.4955 imperial quart per hours.

Frequently asked questions
How many imperial quart per hours are in 1 gallon per seconds?
1 gallon per seconds equals 11,990.50826 imperial quart per hours, using the exact defined conversion factor rather than an estimate.

Multiply the gallon per seconds value by 11990.50826. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per hours back to gallon per seconds?
Use the reverse factor: 1 imperial quart per hours equals 0.0000833993 gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
What is a imperial quart per hours?
Imperial quart per Hours (imp qt/h) is a unit of flow rate.
Is the gallon per seconds to imperial quart per hours conversion exact?
Yes. Both gallon per seconds and imperial quart per hours are defined by fixed standards rather than physical artifacts, so the factor of 11990.50826 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.
