About Converting Cubic Meter per Hours to Imperial quart per Days
Cubic Meter per Hours and Imperial quart per Days 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 days = cubic meter per hours × 21117.0478367
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 days equals 1.31542e-8 base units, so dividing one by the other gives the direct cubic meter per hours-to-imperial quart per days factor of 21117.0478367.
Simple example
1 m3/h × 21117.04784 = 21,117.04784 imp qt/d
1 cubic meter per hours = 21,117.04784 imperial quart per days.
Real-world example
60 m3/h × 21117.04784 = 1,267,022.87 imp qt/d
60 cubic meter per hours = 1,267,022.87 imperial quart per days.

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 days?
Imperial quart per Days (imp qt/d) is a unit of flow rate.
Is the cubic meter per hours to imperial quart per days conversion exact?
Yes. Both cubic meter per hours and imperial quart per days are defined by fixed standards rather than physical artifacts, so the factor of 21117.04784 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.
