How to Convert Cubic Meter per Second to Cubic Meter per Hour
- 1 m³/s = 3600 m³/h
- 1 m³/h = 0.0002777777778 m³/s
- Example: convert 15 m³/s to m³/h: 15 m³/s = 15 × 3600 m³/h = 54000 m³/h
Formula
m³/h = m³/s × 3600
Derivation from SI units:
- 1 m³/s = 1 m³ ÷ 1 s
- 1 m³/h = 1 m³ ÷ 3600 s
Both units are defined exactly, so the factor is exact. Cubic Meter per Second definition: cubic meter per second; Cubic Meter per Hour definition: cubic meter per hour.
Worked examples
- 1 m³/s is exactly 3600 m³/h.
1 m³/s × 3600 = 3600 m³/h - 0.944 m³/s, the ISO 16890 rated flow for a full-size filter, is 3398.4 m³/h.
0.944 m³/s × 3600 = 3398.4 m³/h

Where it's used
SI flows in m³/s are converted to m³/h because most fan, filter and pump catalogues are written in cubic metres per hour.
