Convert Liters per Second to Cubic Centimeters per Second
1 liter per second (L/s) equals 1000 cubic centimeters per second (cm³/s).
1 L/s = 1000 cm³/s
Type in either box. Scientific notation works: 1.5e-3.

How to Convert Liter per Second to Cubic Centimeter per Second
- 1 L/s = 1000 cm³/s
- 1 cm³/s = 0.001 L/s
- Example: convert 15 L/s to cm³/s: 15 L/s = 15 × 1000 cm³/s = 15000 cm³/s
Formula
cm³/s = L/s × 1000
Derivation from SI units:
- 1 L/s = 10⁻³ m³ ÷ 1 s
- 1 cm³/s = 10⁻⁶ m³ ÷ 1 s
- 1 L/s = 0.001 m³/s ÷ 0.000001 m³/s per cm³/s = 1000 cm³/s
Both units are defined exactly, so the factor is exact. Liter per Second definition: liter per second; Cubic Centimeter per Second definition: cubic centimeter per second.
Worked examples
- A reading of 5 L/s converts to 5000 cm³/s.
5 L/s × 1000 = 5000 cm³/s - A value of 50 L/s is 50000 cm³/s.
50 L/s × 1000 = 50000 cm³/s

Where it's used
Liters per Second are used for ventilation rates per person (ASHRAE 62.1, EN 16798), 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.

Frequently asked questions
How many cubic centimeters per second are in 1 liter per second?
1 L/s = 1000 cm³/s.
How do I convert liters per second to cubic centimeters per second?
Multiply the value in L/s by 1000. For example, 15 L/s × 1000 = 15000 cm³/s.
Is the L/s to cm³/s conversion exact?
Yes. Both units are defined exactly, and 1 L/s is exactly 1000 cm³/s.
