Frequently Asked Questions
How much is 255 mg/L in ppm?
255 mg/L equals 255 ppm for water and dilute aqueous solutions (density ≈ 1 kg/L).
How do I convert 255 mg/L to ppm?
For water: 255 mg/L = 255 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.
