Example: 2000ppb is equal to 2ppm: ppm = 2000ppb / 1000 = 2ppm. Simply! ppm = ppb/1,000, and ppb = (1,000)ppm.

Meant to be used in both the teaching and research laboratory, this calculator (see below) can be utilized to perform dilution calculations when working with solutions having the following concentration units: parts per billion (ppb), parts per million (ppm), parts per thousand (ppt), and parts per hundred (pph, %).

If you're having trouble converting something, this is where you should post. ppm = 1mg /L millimolar = millimol /l There is no direct conversion between these two , It varies with the compound dissolved: Take NaCl : Molar mass 58.5g/mol 1ppm NaCl = 1mg/L NaCl = 0.001g/58.5g/mol *1000mM/M = 0.017millimolar. Compare this to 1000 ppb = 1 ppm = 1 mg/kg.

How to convert ppb to ppm. The part P in ppm is equal to the part P in ppb divided by 1000: P (ppm) = P (ppb) / 1000. For example. Find how many ppm are in 9ppb: P (ppm) = 9ppb / 1000 = 0.009ppm. How to convert ppm to ppb. The part P in ppb is equal to the part P in ppm times 1000: P (ppb) = P (ppm) × 1000. For example. Find how many ppb are in 8ppm:

ppm is dimensionless quantity, a ratio of 2 quantities of the same unit..
