What is ppm converter

A ppm (parts per million) converter is a tool that allows you to convert various units of measurement to parts per million. The converter takes a value in one unit and converts it into the equivalent value in ppm.

The units that can be converted to ppm include percent (%), parts per billion (ppb), parts per trillion (ppt), and many others. By using the appropriate conversion factor for each unit, the converter performs the necessary calculation to obtain the ppm value.

For example, if you have a concentration in percent (%), the converter will multiply the percentage by 10,000 to obtain the ppm value. Similarly, for ppb, the converter divides the ppb value by 1,000 to convert it to ppm.

With a ppm converter, you can easily switch between different units of measurement and get the corresponding ppm value.

How to convert ppt to ppm

ppm and ppt are defined as:

1ppm = 1/106 = 10-6

1ppt = 1/1012 = 10-12


1ppm = 106ppt

The number of parts-per million xppm is equal to the number of parts-per trillion xppt divided by 106:

xppm = xppt / 106

Example: 7000ppt is equal to 0.007000ppm:

xppt = 7000ppt / 106 = 0.007ppm
