About Converting Cubic Meter per Seconds to Cubic Meter per Hours
Cubic Meter per Seconds 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. Cubic Meter per Seconds is typically associated with used internationally in hydrology and large-scale water-resource engineering, while Cubic Meter per Hours is typically associated with standard flow-rate unit for HVAC and industrial equipment ratings internationally, outside the US.
Formula
cubic meter per hours = cubic meter per seconds × 3600
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per seconds equals 1 base unit, and 1 cubic meter per hours equals 0.000277777777778 base units, so dividing one by the other gives the direct cubic meter per seconds-to-cubic meter per hours factor of 3600.
Simple example
1 m3/s × 3600 = 3,600 m3/h
1 cubic meter per seconds = 3,600 cubic meter per hours.
Real-world example
60 m3/s × 3600 = 216,000 m3/h
60 cubic meter per seconds = 216,000 cubic meter per hours.
Conversion table
| Cubic Meter per Seconds (m3/s) | Cubic Meter per Hours (m3/h) |
|---|---|
| 0.1 m3/s | 360 m3/h |
| 1 m3/s | 3,600 m3/h |
| 10 m3/s | 36,000 m3/h |
| 60 m3/s | 216,000 m3/h |
| 100 m3/s | 360,000 m3/h |
| 1,000 m3/s | 3,600,000 m3/h |
Reverse conversion: Cubic Meter per Hours to Cubic Meter per Seconds
1 m3/h × 0.0002777777778 = 0.0002777778 m3/s
1 cubic meter per hours = 0.0002777778 cubic meter per seconds.
cubic meter per seconds = cubic meter per hours × 0.000277777777778

Frequently asked questions
How many cubic meter per hours are in 1 cubic meter per seconds?
1 cubic meter per seconds equals 3,600 cubic meter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per seconds to cubic meter per hours?
Multiply the cubic meter per seconds value by 3600. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per hours back to cubic meter per seconds?
Use the reverse factor: 1 cubic meter per hours equals 0.0002777778 cubic meter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per seconds?
Cubic Meter per Seconds (m3/s) measures volumetric flow rate. The SI coherent unit for volumetric flow rate — one cubic meter of volume passing a point every second. It is classified as a SI coherent derived unit.
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 seconds to cubic meter per hours conversion exact?
Yes. Both cubic meter per seconds and cubic meter per hours are defined by fixed standards rather than physical artifacts, so the factor of 3600 used above is exact to as many digits as you choose to display.
Where is the cubic meter per seconds still used today?
Used internationally in hydrology and large-scale water-resource engineering
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.
