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

How to Convert SLPM to Liter per Minute
- 1 SLPM = 1 L/min
- 1 L/min = 1 SLPM
- Example: convert 15 SLPM to L/min: 15 SLPM = 15 × 1 L/min = 15 L/min
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/min = SLPM × 1
Derivation from SI units:
- 1 SLPM = 10⁻³ m³ ÷ 60 s, measured at standard reference conditions
- 1 L/min = 10⁻³ m³ ÷ 60 s
- 1 SLPM = 0.00001666666666667 m³/s ÷ 0.00001666666666667 m³/s per L/min = 1 L/min
- 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 Minute definition: liter per minute.
Worked examples
- 10 SLPM at reference conditions is 10 L/min of actual flow.
10 SLPM × 1 = 10 L/min - A mass flow meter reading 50 SLPM corresponds to 50 L/min when the gas is at reference conditions.
50 SLPM × 1 = 50 L/min

Where it's used
Mass flow meters read SLPM; rotameters and volume meters read actual L/min. Convert with the condition fields when the gas is warmer, colder or at a different pressure than the reference.

Frequently asked questions
What is the difference between SLPM and LPM?
SLPM is referenced to standard conditions (e.g. 0 °C, 101.325 kPa); LPM is the actual volume at line conditions. At 0 °C and 6 bar(g), 100 SLPM occupies only about 14 L/min.
How many liters per minute are in 1 SLPM?
1 SLPM = 1 L/min (reference conditions 0 °C and 101.325 kPa, with the gas at those conditions).
How do I convert SLPM to liters per minute?
Multiply the value in SLPM by 1. For example, 15 SLPM × 1 = 15 L/min.
Is the SLPM to L/min conversion exact?
Yes. Both units are defined exactly, and 1 SLPM is exactly 1 L/min.
