When considering mass, 1 ppm would be one milligram per kilogram. However, in chemistry formulations, a ppm designation assigned to a liquid is understood to mean 1 milligram of a solute present in 1 liter of a substance. A ppm (part per million) is the same as 0.0001% percent.

The alarm thresholds, set by CO concentration measured in parts per million (ppm), are: no alarm below 30 ppm until after 30 days; 70 ppm for one to four hours (but not less than one hour); 150 ppm for 10 to 50 minutes; 400 ppm for four to 15 minutes.
