LEL = 5% methane = 50,000 ppm methane. 10% LEL = % methane = 5000 ppm methane. 1% LEL = % methane = 500 ppm methane. Thumb rule for dummies. Multiply the LEL percentage number by 10,000 to get PP M. To convert from PPM to an LEL percentage, divide the PPM by 10,000. Email ThisBlogThis!Share to TwitterShare to FacebookShare to Pinterest.
Sep 18, 2017· 300ppm of propane, its LEL is , that is, %LEL=300ppm/( vol%＊100)=% LEL propane Meaning ppm means one millionth Vol% means one hundredth That is, 10000ppm = 1Vol% % LEL means the lower limit of explosion, that is, in which concentration will the combustible gas explode when it meets fire. It is worth noticing that this unit is not ...

Concentrations can also be expressed as parts per million (ppm) or parts per billion (ppb) by using a conversion factor. This conversion factor is based on the molecular weight of the chemical and it is different for every chemical. The temperature of the atmosphere also has an influence on the calculation. ...
