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
