About Converting Imperial gallon per Hours to Quart per Seconds
Imperial gallon per Hours and Quart 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
quart per seconds = imperial gallon per hours × 0.00133438880612
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per hours equals 0.00000126280277778 base units, and 1 quart per seconds equals 0.000946352946 base units, so dividing one by the other gives the direct imperial gallon per hours-to-quart per seconds factor of 0.00133438880612.
Simple example
1 imp gal/h × 0.001334388806 = 0.0013343888 qt/s
1 imperial gallon per hours = 0.0013343888 quart per seconds.
Real-world example
60 imp gal/h × 0.001334388806 = 0.0800633284 qt/s
60 imperial gallon per hours = 0.0800633284 quart per seconds.

How do I convert quart per seconds back to imperial gallon per hours?
Use the reverse factor: 1 quart per seconds equals 749.4067662 imperial gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per hours?
Imperial gallon per Hours (imp gal/h) is a unit of flow rate.
What is a quart per seconds?
Quart per Seconds (qt/s) is a unit of flow rate.
Is the imperial gallon per hours to quart per seconds conversion exact?
Yes. Both imperial gallon per hours and quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.001334388806 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.
