So. x (ppm) = 10000 ⋅ x (%) Example: find how many ppm are in 1.7%. x (ppm) = 10000 ⋅ 1.7% = 17000ppm. Percent to ppm … To convert mg/m 3 to ppm at other temperatures and pressures, one must calculate the volume of 1 gram molecular weight of an airborne contaminant (e.g. 92.13 grams of toluene) by using the formula: V = (RT/ P) where R is the ideal gas constant; T is the temperature in kelvins (273.16 + T°C); and P is the pressure in mm Hg. Search results for SILICIO 100 PPM at Sigma-Aldrich ppm or better. This Guide is concerned with application to small to medium size molecules and resulted from a review1 of accurate mass applications which was undertaken as part of the VIMMS Programme. The review1 highlighted the recent rapid growth in the use of mass spectrometry for molecular weight determinations of small to medium sized Tricky question.
