Calculate the missing value between MCG, volume, and PPM using any two inputs, with mass in mcg, mg, or g and volume in m³, liters, or gallons.
| PPM → MCG (in 1 L) | MCG → PPM (in 1 L) |
|---|---|
| 0.1 ppm = 100 mcg | 75 mcg = 0.075 ppm |
| 0.25 ppm = 250 mcg | 150 mcg = 0.15 ppm |
| 0.5 ppm = 500 mcg | 300 mcg = 0.3 ppm |
| 1 ppm = 1,000 mcg | 750 mcg = 0.75 ppm |
| 2 ppm = 2,000 mcg | 1,500 mcg = 1.5 ppm |
| 5 ppm = 5,000 mcg | 3,000 mcg = 3 ppm |
| 10 ppm = 10,000 mcg | 7,500 mcg = 7.5 ppm |
| 25 ppm = 25,000 mcg | 15,000 mcg = 15 ppm |
| 50 ppm = 50,000 mcg | 30,000 mcg = 30 ppm |
| 100 ppm = 100,000 mcg | 60,000 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. | |
| PPM → MCG (in 1 gal) | MCG → PPM (in 1 gal) |
|---|---|
| 0.1 ppm = 378.541 mcg | 500 mcg = 0.1321 ppm |
| 0.25 ppm = 946.3525 mcg | 1,000 mcg = 0.2642 ppm |
| 0.5 ppm = 1,892.705 mcg | 2,000 mcg = 0.5284 ppm |
| 1 ppm = 3,785.41 mcg | 5,000 mcg = 1.321 ppm |
| 2 ppm = 7,570.82 mcg | 10,000 mcg = 2.642 ppm |
| 5 ppm = 18,927.05 mcg | 20,000 mcg = 5.284 ppm |
| 10 ppm = 37,854.1 mcg | 50,000 mcg = 13.21 ppm |

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
