###### ppm Calculator

**THEORY BEHIND CALCULATIONS:**

**FOR METHOD1:** Calculations are based on the following relation:

C(ppm) = 1000000 × msolute / (msolvent + msolute)

Where msolute = Mass of solute, msolvent = Mass of solvent

**FOR METHOD2/3:** Calculations are based on the following relation:

x(ppm) = 10000 ⋅ x(%)

Where x(ppm) = Chemical concentration in ppm, x(%) = Percent of chemical.
