How to Convert Cubic Meter per Hour to Cubic Meter per Second
- 1 m³/h = 0.0002777777778 m³/s
- 1 m³/s = 3600 m³/h
- Example: convert 15 m³/h to m³/s: 15 m³/h = 15 × 0.0002777777778 m³/s = 0.004166666667 m³/s
Formula
m³/s = m³/h ÷ 3600
Derivation from SI units:
- 1 m³/h = 1 m³ ÷ 3600 s
- 1 m³/s = 1 m³ ÷ 1 s
Both units are defined exactly, so the factor is exact. Cubic Meter per Hour definition: cubic meter per hour; Cubic Meter per Second definition: cubic meter per second.
Worked examples
- 3400 m³/h is 0.9444444444 m³/s.
3400 m³/h × 0.0002777777778 = 0.9444444444 m³/s - 36000 m³/h is 10 m³/s.
36000 m³/h × 0.0002777777778 = 10 m³/s
