User Guide

This conversion tool will convert a measurement of leakage rate(QL) for a gas filled or a vacuum sealed volume into the following leak rate units:

  • millibar litres per second (mbar·L/s)
  • pascal cubic metres per second (Pa·m³/s)
  • pascal litres per second (Pa·L/s)
  • standard litres per minute (atm·L/min, slm, slpm)
  • standard cubic millimetres per second (atm·mm³/s)
  • standard cubic centimetres per second (atm·cm³/s, sccs)
  • standard cubic centimetres per minute (atm·cm³/min, sccm)
  • standard cubic centimetres per hour (atm·cm³/h)
  • standard cubic metres per minute (atm·m³/min)
  • standard cubic feet per minute (atm·ft³/min)
  • standard cubic feet per year (atm·ft³/yr)
  • micron of mercury litres per second (µHg·L/s, lusec)
  • micron of mercury cubic feet per minute (µHg·ft³/min, µHg·cfm)
  • micron of mercury cubic feet per hour (µHg·ft³/h)
  • torr litres per second (Torr·L/s)

Leakage rate is a measure of the pressure change due to a leak, multiplied by the volume of the space being tested, and divided by duration of time for the pressure difference to occur.

The basic formula to determine the leakage rate is QL = ΔP·V/Δt).
