Looking for a quick and accurate way to convert PPM to mg/kg? Our free and easy-to-use PPM to mg/kg calculator helps students, scientists, engineers, and researchers perform instant conversions with zero hassle.
Just input the value in PPM, and the calculator instantly gives you the equivalent in mg/kg.
What is PPM and mg/kg?
- PPM stands for parts per million, a common unit for measuring very dilute concentrations in air, water, or soil.
- mg/kg stands for milligrams per kilogram, and it’s functionally equivalent to ppm in most scientific contexts.
Note: 1 ppm = 1 mg/kg for substances in water or soil, which makes this a 1-to-1 conversion.

How to Convert PPM to mg/kg Manually
To convert from PPM to mg/kg, here’s the basic formula:
mg/kg = ppm × 1
For example:
- 50 ppm = 50 mg/kg
- 120 ppm = 120 mg/kg
- 0.7 ppm = 0.7 mg/kg

FAQS
1. How do you convert ppm to mg/kg?
To convert ppm (parts per million) to mg/kg (milligrams per kilogram), you simply use a 1-to-1 ratio:
1 ppm = 1 mg/kg
2. Is 1 ppm equal to 1 mg/kg?
Yes, 1 ppm is equal to 1 mg/kg under standard conditions, especially in solutions or solids like soil and food. This is because both units express a ratio of mass per unit mass—milligrams of substance per kilogram of material.
Difference between ppm and mg/kg?
Technically, both ppm and mg/kg express the same concentration when dealing with solids or liquids:
- ppm (parts per million) is a dimensionless ratio.
- mg/kg (milligrams per kilogram) is a mass-based unit.
The difference is mostly in notation and usage, not in value. For gases, ppm may also refer to volume-based ratios, but for water, soil, or food, they are functionally identical.
