Concentration unit conversion calculator

Conversion formula for concentration units:

1. When concentration = 1000.d mass percent concentration / E

2. Percent by mass concentration = equivalent concentration E/1000.d

3. Molar concentration = 1000.d mass percent concentration / M

4. Mass percent concentration = mass - volume concentration (mg / liter) / 104.d

5. 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
