Cubic Meter per Hour (m³/h)
The cubic metre per hour (m³/h) is the volume in cubic metres that passes in one hour; 1 m³/h = 1/3600 m³/s.
Symbol: m³/h (ASCII: m3/h)
Quantity: volumetric flow rate (volume per unit time)
SI relation: 1 m³/h = 0.0002777777777778 m³/s (exact)
Derivation: 1 m³/h = 1 m³ ÷ 3600 s
Exact: yes, by definition
Typical uses
- Air-handling unit and fan ratings in Europe and Asia
- Pump flow rates and water metering
- Filter rated airflow (3400 m³/h for a full-size 592 × 592 mm filter)
