General Science

Concentration Converter

Convert dilute-solution concentration between mg/L, g/L, µg/L, ppm, ppb, ppt, and % w/v for lab reporting, water quality, and formulation checks.

Density Converter

Convert density between kg/m³, g/cm³, g/mL, kg/L, lb/ft³, lb/in³, lb/US gal, oz/in³, and slug/ft³ for materials, chemistry, and engineering work.

PPM to mg/L Converter

Convert ppm and mg/L for dilute aqueous solutions, with related ppb, µg/L, g/L, and percent outputs for water-quality workflows.

Solution Concentration Converter

Convert solution strength between g/L, mg/L, µg/L, kg/L, g/mL, mg/mL, % w/v, and oz/gal for formulation and lab-prep work.
