Concentration unit conversion calculator
Conversion formula for concentration units:
When concentration = 1000.d mass percent concentration / E
Percent by mass concentration = equivalent concentration E/1000.d
Molar concentration = 1000.d mass percent concentration / M
Mass percent concentration = mass - volume concentration (mg / liter) / 104.d
Mass-volume concentration (mg/L) = 104 mass percent concentration
Ppm is the percentage of mass, ppm = mg / kg = mg / L ie: 1ppm = 1ppm = 1000ug / L
1ppb=1ug/L=0.001mg
In the formula:
E - the gram equivalent of the solute;
d - the specific gravity of the solution;
M - the molar mass of the solute
