About Converting Imperial quart per Hours to Gallon per Seconds
Imperial quart per Hours and Gallon per Seconds 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
gallon per seconds = imperial quart per hours × 0.0000833993003823
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per hours equals 3.157007e-7 base units, and 1 gallon per seconds equals 0.003785411784 base units, so dividing one by the other gives the direct imperial quart per hours-to-gallon per seconds factor of 0.0000833993003823.
Simple example
1 imp qt/h × 0.00008339930038 = 0.0000833993 gal/s
1 imperial quart per hours = 0.0000833993 gallon per seconds.
Real-world example
60 imp qt/h × 0.00008339930038 = 0.005003958 gal/s
60 imperial quart per hours = 0.005003958 gallon per seconds.

Frequently asked questions
How many gallon per seconds are in 1 imperial quart per hours?
1 imperial quart per hours equals 0.0000833993 gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per hours to gallon per seconds?
Multiply the imperial quart per hours value by 0.00008339930038. The converter above does this instantly to whatever precision you set.
How do I convert gallon per seconds back to imperial quart per hours?
Use the reverse factor: 1 gallon per seconds equals 11,990.50826 imperial quart per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial quart per hours?
Imperial quart per Hours (imp qt/h) is a unit of flow rate.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
Is the imperial quart per hours to gallon per seconds conversion exact?
Yes. Both imperial quart per hours and gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.00008339930038 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.
