About Converting Cubic Meter per Hours to Imperial quart per Seconds
Cubic Meter per Hours and Imperial 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. Cubic Meter per Hours is most often used for hvac equipment airflow and liquid-flow ratings.
Formula
imperial quart per seconds = cubic meter per hours × 0.244410275888
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per hours equals 0.000277777777778 base units, and 1 imperial quart per seconds equals 0.0011365225 base units, so dividing one by the other gives the direct cubic meter per hours-to-imperial quart per seconds factor of 0.244410275888.
Simple example
1 m3/h × 0.2444102759 = 0.2444102759 imp qt/s
1 cubic meter per hours = 0.2444102759 imperial quart per seconds.
Real-world example
60 m3/h × 0.2444102759 = 14.66461655 imp qt/s
60 cubic meter per hours = 14.66461655 imperial quart per seconds.

Frequently asked questions
How many imperial quart per seconds are in 1 cubic meter per hours?
1 cubic meter per hours equals 0.2444102759 imperial quart per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per hours to imperial quart per seconds?
Multiply the cubic meter per hours value by 0.2444102759. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per seconds back to cubic meter per hours?
Use the reverse factor: 1 imperial quart per seconds equals 4.091481 cubic meter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per hours?
Cubic Meter per Hours (m3/h) measures volumetric flow rate. One cubic meter of volume passing a point every hour — a common scale for equipment and system flow ratings. It is classified as a metric derived flow-rate unit.
What is a imperial quart per seconds?
Imperial quart per Seconds (imp qt/s) is a unit of flow rate.
Is the cubic meter per hours to imperial quart per seconds conversion exact?
Yes. Both cubic meter per hours and imperial quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.2444102759 used above is exact to as many digits as you choose to display.
Where is the cubic meter per hours still used today?
Standard flow-rate unit for HVAC and industrial equipment ratings internationally, outside the US
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.
