| From: | To: | 
Definition: This calculator converts concentration measurements from parts per million (ppm) to percent (%).
Purpose: It helps scientists, engineers, and technicians easily convert between these common concentration units.
The calculator uses the formula:
Where:
Explanation: Since 1% equals 10,000 ppm, we divide the ppm value by 10,000 to get the equivalent percentage.
Details: Different industries use different units, and this conversion is essential when comparing measurements or following specifications that use different units.
Tips: Simply enter the PPM value (must be ≥ 0) and click Calculate to get the percentage equivalent.
                    Q1: What does ppm stand for?
                    A: PPM stands for "parts per million" - 1 ppm means 1 part of substance per 1 million parts of the whole.
                
                    Q2: When would I need to convert ppm to percent?
                    A: When working with concentration standards, chemical solutions, or air quality measurements that use different units.
                
                    Q3: What's the relationship between ppm and percent?
                    A: 1% = 10,000 ppm, so 1 ppm = 0.0001%.
                
                    Q4: Can I convert percent back to ppm?
                    A: Yes, multiply the percent value by 10,000 to get ppm.
                
                    Q5: What's the precision of this calculator?
                    A: Results are displayed with 6 decimal places to handle very small concentrations accurately.
