How To Convert MV To PPM

A millivolt, or mV, is a unit of measurement equal to one-thousandth of a volt. Ppm refers to parts per million, and is a way to describe dilute concentrations of a substance — usually in soil or water. Converting between one unit and another poses challenges by hand, because of the miniscule decimals involved; one millivolt is equal to 11.000000e-03 PPM. An online calculator can help you convert between the two units in a snap.

Step 1

Navigate to the Free University's Conversion of Units Calculator.

Step 2

Scroll down to mV in the "From" scroll box and then click "mV."

Step 3

Scroll down to the "To" scroll box and then click "ppm."

Step 4

Type the number of mV you want to convert into the "From" text box and then click "Submit." The result will appear on the first line in a new page. For example, 99 mV converted to ppm results in 9.900000e-02.
