How to Convert Cubic Centimeter per Second to Liter per Second
- 1 cm³/s = 0.001 L/s
- 1 L/s = 1000 cm³/s
- Example: convert 15 cm³/s to L/s: 15 cm³/s = 15 × 0.001 L/s = 0.015 L/s
Formula
L/s = cm³/s ÷ 1000
Derivation from SI units:
- 1 cm³/s = 10⁻⁶ m³ ÷ 1 s
- 1 L/s = 10⁻³ m³ ÷ 1 s
- 1 cm³/s = 0.000001 m³/s ÷ 0.001 m³/s per L/s = 0.001 L/s
Both units are defined exactly, so the factor is exact. Cubic Centimeter per Second definition: cubic centimeter per second; Liter per Second definition: liter per second.
Worked examples
- A reading of 2 cm³/s converts to 0.002 L/s.
2 cm³/s × 0.001 = 0.002 L/s - A value of 50 cm³/s is 0.05 L/s.
50 cm³/s × 0.001 = 0.05 L/s

Where it's used
Cubic Centimeters per Second are used for air permeability testers that report flow before dividing by area, while liters per second appear in ventilation rates per person (ASHRAE 62.1, EN 16798). Both measure volumetric flow rate (volume per unit time), so the conversion is a fixed factor.

Frequently asked questions
How many liters per second are in 1 cubic centimeter per second?
1 cm³/s = 0.001 L/s.
How do I convert cubic centimeters per second to liters per second?
Multiply the value in cm³/s by 0.001, or divide it by 1000. For example, 15 cm³/s × 0.001 = 0.015 L/s.
Is the cm³/s to L/s conversion exact?
Yes. Both units are defined exactly, and 1 cm³/s is exactly 0.001 L/s.
