Convert 79 PPM to mg/L | 79 ppm = 79 mg/L
Quick Answer: 79 ppm = 79 mg/L
Scope: This converter is for liquid solutions. Do not use it for gas-phase ppmv conversions, which depend on temperature, pressure, and molecular weight.
Note: ppm equals mg/L only when the solution density is approximately 1 kg/L (true for most dilute aqueous solutions). For denser solutions like concentrated sulfuric acid (1.839 kg/L) or brine, use the substance selector or enter a custom density above.

Frequently Asked Questions
How much is 79 ppm in mg/L?
79 ppm equals 79 mg/L for water and dilute aqueous solutions (density ≈ 1 kg/L).
How do I convert 79 ppm to mg/L?
For water: 79 ppm = 79 mg/L (they are numerically equal). General formula: mg/L = ppm × density (kg/L).
Are ppm and mg/L always equal?
Only for water and dilute aqueous solutions where density ≈ 1 kg/L. For other solutions (concentrated acids, brines, organic solvents), multiply ppm by the solution density to get mg/L.
Method note: ppm (mass ratio) and mg/L (mass per volume) are numerically equal only for water-like solutions where density ≈ 1 kg/L — the common case for drinking water, dilute aqueous samples, and most environmental water quality data. For denser or less dense liquids, apply mg/L = ppm × density (kg/L). This page does not cover gas-phase ppmv, which depends on temperature, pressure, and molecular weight.
Density values for the substance selector are drawn from standard chemistry references; conversion factors follow ISO/NIST SI definitions. Figures are rounded for display — use the custom density field for higher precision.
