Parts Per Million Calculator

The Parts Per Million (PPM) Calculator is an essential tool for chemists, engineers, students, and lab technicians to calculate concentration levels in solutions. It simplifies the process of determining PPM, converting between units like PPB, PPT, and Percent, and calculating solute mass based on PPM.

Why Use the PPM Calculator?

Working with solutions often requires precise measurements. Manual calculations can be time-consuming and prone to errors. Using this calculator, you can:

  • Calculate PPM from solute and solution mass
  • Find the mass of solute needed for a specific PPM concentration
  • Convert between PPM, PPB, PPT, and Percent
  • Handle different units such as mg, g, kg, lb, L, mL, and gallons
  • Get results instantly with minimal effort

How to Use the PPM Calculator

Example Calculation

Example 1 – Calculate PPM:

  • Solute: 5 mg
  • Solution: 1 L
  • Units: mg and L

Calculation:

PPM = (5 mg / 1000 g) × 1,000,000 ≈ 5 ppm
PPB = 5 × 1000 = 5000 ppb
PPT = 5 × 1,000,000 = 5,000,000 ppt
Percent = 5 / 10,000 ≈ 0.0005%

Example 2 – Calculate Mass from PPM:

  • PPM: 10 ppm
  • Solution: 2 L
  • Desired unit: mg

Calculation:

Solute Mass = (PPM × Solution Mass) / 1,000,000
Solute Mass = 10 × 2000 g / 1,000,000 = 0.02 g ≈ 20 mg

Example 3 – Convert Units:

  • Convert 5000 PPB to PPM:
PPM = PPB / 1000 = 5000 / 1000 = 5 ppm
