About Converting Cubic Meter per Days to Cubic Meter per Hours
Cubic Meter per Days and Cubic Meter 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
cubic meter per hours = cubic meter per days × 0.0416666666667
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per days equals 0.0000115740740741 base units, and 1 cubic meter per hours equals 0.000277777777778 base units, so dividing one by the other gives the direct cubic meter per days-to-cubic meter per hours factor of 0.0416666666667.
Simple example
1 m3/d × 0.04166666667 = 0.0416666667 m3/h
1 cubic meter per days = 0.0416666667 cubic meter per hours.
Real-world example
60 m3/d × 0.04166666667 = 2.5 m3/h
60 cubic meter per days = 2.5 cubic meter per hours.

Frequently asked questions
How many cubic meter per hours are in 1 cubic meter per days?
1 cubic meter per days equals 0.0416666667 cubic meter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per days to cubic meter per hours?
Multiply the cubic meter per days value by 0.04166666667. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per hours back to cubic meter per days?
Use the reverse factor: 1 cubic meter per hours equals 24 cubic meter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per days?
Cubic Meter per Days (m3/d) is a unit of flow rate.
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.
Is the cubic meter per days to cubic meter per hours conversion exact?
Yes. Both cubic meter per days and cubic meter per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.04166666667 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.
