Question
How to correctly convert the concentration of EGF from percentage (%) to parts per million (ppm)? Specifically, is 5% EGF equivalent to 250 ppm, and what is the correct conversion?
Answer
Regarding the concentration of EGF:
Your calculation that 5% EGF is equal to 250 ppm is incorrect.
To convert percentage concentration to parts per million (ppm), the general rule is that 1% is equivalent to 10,000 ppm.
Therefore, for a 5% concentration of EGF:
5% * 10,000 ppm/% = 50,000 ppm.
The correct concentration of EGF in your formula at 5% is 50,000 ppm.
