Convert values from percentage to parts-per-million (ppm) using our dedicated calculator.
Input the value in percentage and click the 'Convert' button:
Enter a number in percent and press the Convert button:
1% = 10000ppm
So
x(ppm) = 10000 ⋅ x(%)
Example: find how many ppm are in 1.7%.
x(ppm) = 10000 ⋅ 1.7% = 17000ppm

Converting from percent to parts-per-million (ppm) helps in expressing very low concentrations or minute quantities. It is especially useful in fields like chemistry, biology, and environmental science where minute changes can be significant.
