Concentration Units
Common concentration units include:
- Parts per Million (PPM): 1 part in 1,000,000 parts
- Parts per Billion (PPB): 1 part in 1,000,000,000 parts
- Percentage (%): Parts per hundred (1 part in 100)
- Per Mille (‰): Parts per thousand (1 part in 1,000)

FAQs
How do I convert PPM to percentage?
Divide the PPM value by 10,000. For example, 5,000 PPM = 0.5%.
What is the difference between PPM and mg/L?
In dilute aqueous solutions, 1 PPM is approximately equal to 1 mg/L because the density of water is 1 kg/L.
