You may use an HB pencil for any diagrams or graphs. La partie par million (le ppm), terme beaucoup utilisé en sciences (toxicologie, formulation, chimie, métallurgie, électronique, géochimie, etc.), est la fraction valant 10 –6, c'est-à-dire un millionième [a]. On utilise surtout le ppm pour exprimer une fraction massique (1 ppm = 1 mg/kg) [b]. This means that there is 25,000 PPM in 2.5 percent. Use the same procedure when you want to convert new values in percent to get the corresponding results in parts-per-million. The Percent to PPM converter gives quick and accurate results based on the values you enter in the blank text field.

While using these terms one should be very specific and not be confused in using one in place of the other. ppm “ppm” stands for “parts per million”. PPM (Parts per million) is a measurement used today by many customers to measure quality performance. Definition: One PPM means one (defect or event) in a million or 1/1,000,000 There was a time when you were considered a pretty good supplier when your defect rate was less than 1%, (10,000 PPM), then the expectation was increased to 0.1% or 1,000 PPM. ppm↔mg/tsp 1 mg/tsp = 5000 ppm. ppm↔ug/uL 1 ug/uL = 1000 ppm.
