MCG ↔ PPM Conversion Table (Volume = 1 Liter)
PPM → MCG (in 1 L) MCG → PPM (in 1 L)
0.1 ppm = 100 mcg75 mcg = 0.075 ppm
0.25 ppm = 250 mcg150 mcg = 0.15 ppm
0.5 ppm = 500 mcg300 mcg = 0.3 ppm
1 ppm = 1,000 mcg750 mcg = 0.75 ppm
2 ppm = 2,000 mcg1,500 mcg = 1.5 ppm
5 ppm = 5,000 mcg3,000 mcg = 3 ppm
10 ppm = 10,000 mcg7,500 mcg = 7.5 ppm
25 ppm = 25,000 mcg15,000 mcg = 15 ppm
50 ppm = 50,000 mcg30,000 mcg = 30 ppm
100 ppm = 100,000 mcg60,000 mcg = 60 ppm
Formulas (as used by the calculator): M(µg) = PPM × V(m³) × 1,000,000 and PPM = M(µg) ÷ (V(m³) × 1,000,000). 1 L = 0.001 m³.

MCG To PPM Formula

The following formula is used to calculate PPM from MCG.

PPM = MCG / (10^6V)
  • 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
