Convert Cubic Centimeters per Second to m³/h

Formula

m³/h = cm³/s × 0.0036

or m³/h = cm³/s ÷ 277.7777777778

Derivation from SI units:

• 1 cm³/s = 10⁻⁶ m³ ÷ 1 s
• 1 m³/h = 1 m³ ÷ 3600 s
• 1 cm³/s = 0.000001 m³/s ÷ 0.0002777777777778 m³/s per m³/h = 0.0036 m³/h

Both units are defined exactly, so the factor is exact. Cubic Centimeter per Second definition: cubic centimeter per second; Cubic Meter per Hour definition: cubic meter per hour.

Worked examples

1. A reading of 2 cm³/s converts to 0.0072 m³/h.
   2 cm³/s × 0.0036 = 0.0072 m³/h
2. A value of 50 cm³/s is 0.18 m³/h.
   50 cm³/s × 0.0036 = 0.18 m³/h

Where it's used

Cubic Centimeters per Second are used for air permeability testers that report flow before dividing by area, while cubic meters per hour appear in air-handling unit and fan ratings in Europe and Asia. Both measure volumetric flow rate (volume per unit time), so the conversion is a fixed factor.
