Convert PPTH to mg/kg easily using our simple calculator. Learn the formula, see step-by-step examples, and understand PPTH to mg/kg conversion clearly for soil, water, and chemical analysis.
When working with very small concentrations of a substance, units like PPTH (parts per thousand) and mg/kg (milligrams per kilogram) are commonly used. These units are especially important in environmental testing, soil analysis, water quality, agriculture, and chemistry.
This calculator helps you quickly convert PPTH to mg/kg without confusion.
What is PPTH?
PPTH (Parts Per Thousand) means:
- 1 part of a substance per 1,000 parts of the total material
It is used when concentrations are higher than PPM but still relatively small.
What is mg/kg?
mg/kg (Milligrams per Kilogram) means:
- Milligrams of a substance present in 1 kilogram of material
This unit is widely used in:
- Soil testing
- Food safety
- Chemical analysis
Relationship Between PPTH and mg/kg
To convert PPTH to mg/kg, we use the fact that:
- 1 kilogram = 1,000,000 milligrams
- 1 PPTH = 1 part per 1,000
So, the conversion becomes very straightforward.
PPTH to mg/kg Formula
Formula
mg/kg=PPTH×1000
Why Multiply by 1000?
Because:
- PPTH is based on 1,000 units
- mg/kg is based on 1,000,000 mg per kg
So each 1 PPTH equals 1000 mg/kg.
Example Conversion
Example Problem
Convert 2.5 PPTH to mg/kg.
Solution Formula
mg/kg=2.5×1000
Final Answer
mg/kg=2500
Final Example (Written Clearly)
If a soil sample contains 2.5 PPTH of a chemical, it means the concentration is:
2500 mg/kg
When Should You Use This Calculator?
Use a PPTH to mg/kg calculator when:
- Reading lab reports
- Converting environmental test data
- Working with soil, water, or chemical samples
- Avoiding manual calculation errors
