Calculating PPM
The formula for calculating PPM is:
PPM = (Mass of Solute / Mass of Solution) × 1,000,000
Example Calculation
Suppose you have 0.002 grams of salt in 1 liter of water:
- Convert to grams (1 liter = 1000 grams)
- Apply formula: (0.002/1000) × 1,000,000 = 2 PPM
Project Portfolio Management 💼
PPM in business contexts involves:
- Prioritizing projects
- Allocating resources effectively
- Aligning projects with organizational goals
- Minimizing risks
"Understanding PPM is essential for anyone working in environmental science, quality control, or regulatory compliance." - Environmental Protection Agency
