Formula and methodology
Formula: mg/L=ppm×density in g/mL; g/L=mg/L/1000.
PPM by mass is a mass fraction, while mg/L is volume-based. The density field makes that distinction visible instead of assuming every solution has water's density.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Concentration — ppm by mass; minimum 0; maximum 1000000000
- Solution density — g/mL; minimum 1.0E-6; maximum 100
Worked example
| Input | Value |
|---|---|
| Concentration | 25 |
| Solution density | 1 |
25 ppm in a 1.000 g/mL solution = 25 mg/L = 0.025 g/L.
Assumptions and limits
- PPM means milligrams of solute per kilogram of solution by mass.
- Density is entered in grams per millilitre at the relevant temperature.
- Sampling, chemical identity, exposure limits, and laboratory uncertainty are not evaluated.
