Converting ug/kg to PPM

Tue Jul 11, 2006 12:14 am

Does anyone know how to convert ug/kg into ppm?

What does 1 ug/kg equal in ppm?

micro = ì = 10e-6
kilo = k = 10e+3
The "difference" is 10e+/-9
ppm = 10e+/-6
The difference is 10e+/-3
so multiply ug/kg by 1000 to get ppm (1 ug/kg = 1000 ppm)
assuming that you mean ppm by weight (mass)
