Convert Liters per Second to SLPM
1 liter per second (L/s) equals 60 SLPM, at the reference conditions 0 °C and 101.325 kPa, with the gas at those conditions.
1 L/s = 60 SLPM

How to Convert Liter per Second to SLPM
- 1 L/s = 60 SLPM
- 1 SLPM = 0.01666666667 L/s
- Example: convert 15 L/s to SLPM: 15 L/s = 15 × 60 SLPM = 900 SLPM
Reference conditions. SLPM: Standard flow: volume the gas would occupy at the standard reference conditions (default 0 °C, 101.325 kPa). Converting to actual flow needs the actual temperature and pressure.
Standard vs actual flow. The values above assume the gas is at the standard reference conditions (0 °C, 101.325 kPa). Set the actual temperature and pressure in the converter to get the real volumetric flow.
Formula
SLPM = L/s × 60
Derivation from SI units:
- 1 L/s = 10⁻³ m³ ÷ 1 s
- 1 SLPM = 10⁻³ m³ ÷ 60 s, measured at standard reference conditions
- 1 L/s = 0.001 m³/s ÷ 0.00001666666666667 m³/s per SLPM = 60 SLPM
- Standard ↔ actual: Q_actual = Q_standard × (T_actual / T_ref) × (P_ref / P_actual), absolute T and P.
Both units are defined exactly, so the factor is exact. Liter per Second definition: liter per second; SLPM definition: SLPM.
Worked examples
- A reading of 5 L/s converts to 300 SLPM.
5 L/s × 60 = 300 SLPM - A value of 50 L/s is 3000 SLPM.
50 L/s × 60 = 3000 SLPM

Where it's used
Liters per Second are used for ventilation rates per person (ASHRAE 62.1, EN 16798), while SLPM appear in mass flow meters and controllers. Both measure volumetric flow rate (volume per unit time), so the conversion is a fixed factor.

Frequently asked questions
How many SLPM are in 1 liter per second?
1 L/s = 60 SLPM (reference conditions 0 °C and 101.325 kPa, with the gas at those conditions).
How do I convert liters per second to SLPM?
Multiply the value in L/s by 60. For example, 15 L/s × 60 = 900 SLPM.
Is the L/s to SLPM conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
