Frequently Asked Questions
How much is 342 mg/L in ppm?
342 mg/L equals 342 ppm for water and dilute aqueous solutions (density ≈ 1 kg/L).
How do I convert 342 mg/L to ppm?
For water: 342 mg/L = 342 ppm (numerically equal). General formula: ppm = mg/L ÷ density (kg/L).
Are mg/L and ppm always equal?
Only for water and dilute aqueous solutions where density ≈ 1 kg/L. For other solutions, divide mg/L by the solution density to get ppm.
