User Guide

This conversion tool will convert a measurement of leakage rate(Q_L) 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 Q_L = ΔP·V/Δt).
