How to Convert SLPM to Liter per Second
- 1 SLPM = 0.01666666667 L/s
- 1 L/s = 60 SLPM
- Example: convert 15 SLPM to L/s: 15 SLPM = 15 × 0.01666666667 L/s = 0.25 L/s
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
L/s = SLPM × 0.01666666666667
or L/s = SLPM ÷ 60
Derivation from SI units:
- 1 SLPM = 10⁻³ m³ ÷ 60 s, measured at standard reference conditions
- 1 L/s = 10⁻³ m³ ÷ 1 s
- 1 SLPM = 0.00001666666666667 m³/s ÷ 0.001 m³/s per L/s = 0.01666666666667 L/s
- 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. SLPM definition: SLPM; Liter per Second definition: liter per second.
Worked examples
- A reading of 2 SLPM converts to 0.03333333333 L/s.
2 SLPM × 0.01666666667 = 0.03333333333 L/s - A value of 50 SLPM is 0.8333333333 L/s.
50 SLPM × 0.01666666667 = 0.8333333333 L/s

Where it's used
SLPM are used for mass flow meters and controllers, 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 SLPM?
1 SLPM = 0.01666666667 L/s (reference conditions 0 °C and 101.325 kPa, with the gas at those conditions).
How do I convert SLPM to liters per second?
Multiply the value in SLPM by 0.01666666667, or divide it by 60. For example, 15 SLPM × 0.01666666667 = 0.25 L/s.
Is the SLPM to L/s 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).
