How to Convert Milligram/L to Parts per million?
We can convert milligram/L to parts per million by using an example.
Example:
Convert 20 Milligram/L to Parts per million?
We know 1 Milligram/L = 1.0000000 parts per million; 1 Parts per million = 1.0000000 milligram/L.
20 milligram/L = ___ppm
20 × 1.0000000 = 20.00000 ppm (we know 1 milligram/L = 1.0000000 parts per million)
Answer:
20 milligram/L = 20.00000 parts per million
How to Convert Milligram/L to Parts per million
- For dilute aqueous solutions, mg/L and PPM are equivalent
- 1 mg/L = 1 PPM (in water at standard conditions)
- Simply use the same numeric value

Technical Details
The mg/L to PPM conversion is a 1:1 ratio for dilute aqueous solutions. The WHO drinking water guidelines specify maximum contaminant levels in mg/L: arsenic at 0.01 mg/L (10 ppb), lead at 0.01 mg/L, fluoride at 1.5 mg/L, and nitrate at 50 mg/L. All of these are numerically identical in PPM.
Frequently Asked Questions
How do I convert mg/L to PPM?
For water, 1 mg/L = 1 PPM. The values are the same.
Is mg/L the same as ppm for all liquids?
Only for liquids with a density close to 1 kg/L (like water). For denser liquids, the conversion requires knowing the density.
Milligram/L to Parts per million Conversion Formula
1 milligram/L = 1.0000000 parts per million
1 parts per million = 1.0000000 milligram/L
Formula: parts per million = milligram/L value × 1.0000000
Reverse: milligram/L = parts per million value × 1.0000000
