PPM Calculator
Calculate parts per million from solute and solution amounts, convert ppm into percent and ppb, or find the solute amount needed for a target concentration.
Calculate ppm, find solute amount, or convert an existing concentration.
Use mass, volume, or direct concentration units that match your problem.
See ppm, percent, ppb, mg/L equivalent, and a clear formula breakdown.
1% = 10,000 ppm
1 ppm = 1,000 ppb
250 mg equals 0.00025 kg. Dividing by 1 kg of total solution and multiplying by 1,000,000 gives 250 ppm. This is equal to 0.025% or 250,000 ppb.
What does ppm mean?
PPM means parts per million. It describes one part of a substance for every one million parts of the total mixture.
Is 1 ppm equal to 1 mg/L?
For dilute water-based solutions with density close to 1 kg/L, 1 ppm is approximately equal to 1 mg/L. For other liquids, density must be considered.
How do I convert ppm to percent?
Divide ppm by 10,000. For example, 500 ppm equals 0.05%.
How do I calculate how much solute to add?
Multiply the target ppm by the total solution mass, then divide by 1,000,000. This calculator also handles volume by using the entered density.
