2018-12-01 · The typical outdoor CO 2 concentrations are approximately 380 ppm, although in urban areas these have been reported to be as high as 500 ppm because of the increased anthropogenic sources (Persily, 1997). The increasing CO 2 concentration contributes to the greenhouse effect and accelerates global warming (Bertoni et al., 2004; Cox et al., 2000

g/kg↔ppm 1 g/kg = 1000 ppm. g/kg↔ppb 1 g/kg = 1000000 ppb. g/kg↔ppt 1 g/kg = 1000000000 ppt. g/kg↔ppq 1 g/kg = 1000000000000 ppq. g/kg↔ug/g 1 g/kg = 1000 ug/g.

380 ppm

Percent to ppm converter How to convert ppm to percent. 1% = 1/100. 1ppm = 1/1000000. So. 1ppm = 0.0001%. So to convert from ppm to percent, divide the ppm by 10000: x (%) = x (ppm) / 10000 . Example: find how many percent are in 300ppm. x (%) = 300ppm / 10000 = 0.03%.

For example, 5 ppm multiplied by is equal to ppt. Best conversion unit for 380 Parts-Per-Million (ppm) We define the "best" unit to convert a number as the unit that is the lowest without going lower than 1.
