What is ppm? ppm is an abbreviation of parts per million. ppm is a value that represents the part of a whole number in units of 1/1000000.. ppm is dimensionless quantity, a ratio of 2 quantities of the same unit.. For example: mg/kg. One ppm is equal to 1/1000000 of the whole:. 1ppm = 1/1000000 = 0.000001 = 1×10-6. One ppm is equal to 0.0001%:. 1ppm = 0.0001%

This Percent to PPM Calculator calculates the parts per million value of an item from the percent value given. For example, if a resistor has a ppm percentage of 10%, this numerical value of 10% represents 100,000 ppm. 0.0001% represents 1 unit out of 1,000,000 (one million) units. Therefore: 1%= 0.01= 0.01 * 1,000,000= 10,000ppm
