What is PPM (Parts Per Million)?
Simple Definition
PPM measures how many parts of a substance exist in one million parts of a solution. Think of it like finding 1 drop in 50 liters of water – that’s approximately 1 PPM. Understanding what is PPM is essential for accurate measurements across industries.
1 PPM = 1 milligram per kilogram (mg/kg)

PPM Calculation Formula
Basic PPM Formula
Worked Example:
Problem: 5 grams of salt dissolved in 1,000 grams of water
Solution: PPM = (5 ÷ 1,005) × 1,000,000 = 4,975 PPM
Total mass = 5g salt + 1,000g water = 1,005g

Common PPM Questions
How do I convert PPM to percentage?
Divide PPM by 10,000 to get percentage. Example: 5,000 PPM ÷ 10,000 = 0.5%. This conversion is essential for understanding concentration levels in various applications.
Use PPM to % Calculator →How do I read PPM results correctly?
Understanding PPM results requires context about what you’re measuring and comparing to safety standards. Different substances have different acceptable limits.
Learn to Read PPM Results →What are safe drinking water PPM levels?
WHO guidelines recommend TDS levels under 500 PPM for drinking water. Specific contaminants have different limits – fluoride should be under 1.5 PPM, nitrates under 50 PPM.
Regional Water Standards →How do I calculate PPM step by step?
PPM calculation involves dividing the mass of solute by total mass of solution, then multiplying by 1,000,000. Our step-by-step guide makes it simple.
