Convert Cubic Meters per Second to cm³/s

Formula

cm³/s = m³/s × 1000000

Derivation from SI units:

• 1 m³/s = 1 m³ ÷ 1 s
• 1 cm³/s = 10⁻⁶ m³ ÷ 1 s

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

Worked examples

1. A reading of 0.5 m³/s converts to 500000 cm³/s.
   0.5 m³/s × 1000000 = 500000 cm³/s
2. A value of 10 m³/s is 10000000 cm³/s.
   10 m³/s × 1000000 = 10000000 cm³/s

Where it's used

Cubic Meters per Second are used for river and channel discharge, while cubic centimeters per second appear in air permeability testers that report flow before dividing by area. Both measure volumetric flow rate (volume per unit time), so the conversion is a fixed factor.
