Standard litre per minute

Standard litre per minute (SLPM or L/min) is a unit of measurement commonly used in various scientific and engineering fields to measure gas flow rates. It indicates the volume of gas flowing per minute at "standard" conditions of temperature and pressure. The "standard" conditions can vary based on context but are often considered to be at a temperature of 0 degrees Celsius (273.15 K) and a pressure of 1 atmosphere (101.325 kPa).
