Part Per Million Converter

Part Per Million Converter

This calculator converter is dedicated to simple parts per million to percent conversions and percent to parts per million   i.e.  ppm   to  % and  % to ppm

Place the value you want to convert in  the box and then chose the conversion tab applicable to your needs
You may find this a handy tool to iindicate the accuracy of an item. A component may be said to have an accuracy of 100 PPM so in this case its value is accurate to within 100 parts in a million or 0.01%.

Note-this is a  parts-per-million calculation (ppm) 106, not parts-per-billion (ppb)  109, not parts-per-trillion (ppt) 1012
