Conversion Formulas with Step-by-Step Calculations
PPT to PPM Formula
PPM = PPT ÷ 1,000
Example: 15,000 ppt to ppm
Step 1: 15,000 ÷ 1,000
Step 2: = 15 ppm
Verification: 15 × 1,000 = 15,000 ppt ✓
PPM to PPT Formula
PPT = PPM × 1,000
Example: 7.5 ppm to ppt
Step 1: 7.5 × 1,000
Step 2: = 7,500 ppt
Verification: 7,500 ÷ 1,000 = 7.5 ppm ✓
Scientific Notation
1 ppm = 1 × 10⁻⁶ (one millionth)
1 ppt = 1 × 10⁻¹² (one trillionth)
Relationship: 1 ppm = 1,000 ppt
Factor difference: 10⁻⁶ ÷ 10⁻¹² = 10⁶ = 1,000,000
Percentage Relations
1% = 10,000 ppm = 10,000,000 ppt
Example: 0.001% to ppt
Step 1: 0.001 × 10,000,000
Step 2: = 10,000 ppt

Practice Problems with Step-by-Step Solutions
Problem 1:
A water sample contains 25,000 ppt of a contaminant. Convert to ppm.
Solution:
• Formula: PPM = PPT ÷ 1,000
• Calculation: 25,000 ÷ 1,000 = 25 ppm
Answer: 25 ppm
Problem 2:
Convert 850,000 ppt of dissolved oxygen to ppm for environmental monitoring.
Solution:
• Formula: PPM = PPT ÷ 1,000
• Calculation: 850,000 ÷ 1,000 = 850 ppm
Answer: 850 ppm
Problem 3:
A pharmaceutical analysis shows 3.75 million ppt of an active ingredient. Find the ppm concentration.
Solution:
• Given: 3,750,000 ppt
• Formula: PPM = PPT ÷ 1,000
• Calculation: 3,750,000 ÷ 1,000 = 3,750 ppm
Answer: 3,750 ppm
Problem 4:
Convert 125,000 ppt to both ppm and percentage for a quality control report.
Solution:
• PPM: 125,000 ÷ 1,000 = 125 ppm
• Percentage: 125,000 ÷ 10,000,000 = 0.0125%
