Enter the total micrograms per cubic meter into the calculator to convert into parts per mille (PPM).

## MCG To PPM Formula

The following formula is used to calculate PPM from MCG.

PPM = MCG / V / 1000

• Where PPM is the parts per mille
• MCG is the total micrograms
• V is the total volume (m^3)

To calculate PPM from MCG, divide the micrograms by the volume, then divide by 1000.

## What is MCG?

Definition:

MCG, short for micro gram, is a unit of measure that is equal to 1 / 1000th of a gram.

To convert this value into PPM, you must know the volume the mass occupies.

## How to calculate PPM from MCG?

Example Problem:

The following example outlines how to calculate PPM from MCG.

First, determine the total amount of micro grams. In this example, there are 5 micrograms.

Next, determine the total amount of volume these micrograms occupy. In this case, the total volume is measured to be 2.5 cubic meters.

Finally, calculate the PPM using the formula above:

PPM = MCG / V / 1000

PPM = 5 / .25 / 1000

PPM = .02
