### LEL and Other Combustible Gas Concentration Units | ChemDAQ

To convert from % LEL to ppm, it is necessary to know the Lower Explosive Limit. Using ethylene oxide (EtO) as an example, the LEL is 3% by volume, which is equal to 30,000 ppm. It is common therefore in facilities that use large amounts of EtO to have two different types of monitor. One set of monitors measures EtO at parts per million concentrations to warn about potentially toxic exposures
