· % vol = 10 ppm % vol = 1 ppm. The % LEL value can be used with the gas name as each gas has its own variable LEL value. If we look it on the example of hydrogen sulfide, which is both toxic and flammable gas: 100% LEL = 4% vol = 40,000 ppm H 2 S 50% LEL = 2% vol = 20,000 ppm H 2 S 10% LEL = % vol = 4,000 ppm H 2 S.

To convert from PPM to an LEL percentage, divide the PPM by 10,000. Step 3 For example, ethylene has an LEL of percent. Multiplying this by 10,000 gives 27,000 PPM as the lower explosive limit, as it would be displayed on a gas meter. Advertisement references ...
To calculate %LEL to ppm example Methane 100%LEL = 5%VOL = 50,000 ppm. To calculate 50% LEL divide ppm of 100%VOL (50000 ppm) by 2 or multiply by .50. To calculate 10% LEL divide ppm by 10 or multiply by .10. URL Name.
LEL sensors measure percent of LEL. For example, Gasoline has an LEL of %. Therefore, 100% of LEL is 14,000 ppm of gasoline, 10% of LEL is 1,400 ppm of gasoline and 1% of LEL is 140 ppm of gasoline. 140 ppm of gasoline is the lowest amount of vapor that the LEL monitor can "see." Gasoline has a TWA of 300 ppm and a STEL of 500 ppm; this does ...
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
To calculate %LEL to ppm example Methane 100%LEL = 5%VOL = 50,000 ppm To calculate 50% LEL divide ppm of 100%VOL(50000 ppm) by 2 or multiply by .50 To calculate 10% LEL divide ppm …
10% LEL = % methane = 5000 ppm methane; 1% LEL = % methane = 500 ppm methane; So here we have three numbers at the alarm level: 10 and and 5000. Without scale they are meaningless. Pretty much all combustible gas monitors are built to be laymanproof. The operator doesn’t need to understand scale or range; they just need to know what to do when the alarm goes off. It’s …
100% 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 …
· Regardless of whether we use the %LEL scale, the percent scale or the ppm scale, the concentration is all the same. 100% LEL = 5% methane = 50,000 ppm methane. 10% LEL = % methane = 5000 ppm methane. 1% LEL = % methane = 500 ppm methane…

Regardless of whether we use the %LEL scale, the percent scale or the ppm scale, the concentration is all the same. 100% LEL = 5% methane = 50,000 ppm methane. 10% LEL = % methane = 5000 ppm methane. 1% LEL = % methane = 500 ppm methane. So here we have three numbers at the alarm level: 10 and and 5000.
· Methane is also measured in ppm (parts per million). The LEL monitoring serves the safety of individuals, because it can be stated that 100% LEL corresponds to 100% risk of explosion. When working in an area above the LEL, an ignition source in combination with oxygen can cause an explosion. In Europe, we have set the LEL of methane at vol.%.
· PPM unit can be converted to LEL as follows: ppm=%LEL * LEL (vol%) *100 For example: 35% LEL of methane, its LEL is 2 vol%, that is, ppm=35(%LEL)*2(vol%)*100=7000ppm methane

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. CONVERT PPM TO MG/M 3. Formula: concentration (mg/m 3) = x concentration (ppm) x molecular weight For example: 100 ppm of NH 3 ( g/mol)
· The unit of measurement used when specifying this amount is %LEL. % by volume of methane gas in the environment can be specified as 50% LEL. 5% methane indicates that the 100% LEL level has been reached and there is a risk of explosion. 5 What is PPM? It is an abbreviation for “parts per million”. Similar to the percentage (%) that is ...
