PPM ⇄ Molarity Calculator
Real-time converter between ppm (mg/kg), molarity (mol/L),
molar mass, and solution density. For water, density ≈ 1 g/mL.

• For aqueous solutions: 1 ppm ≈ 1 mg/L when ρ ≈ 1 g/mL.
• Conversions (general): ppm (mg/kg) → mg/L = ppm × ρ (kg/L); molarity c = (mg/L ÷ 1000) / Mm.
• Inverse: ppm = c × Mm × 1000 / ρ.
