Concentration Converter
How to convert concentration units
- Type the value and choose its unit.
- For conversions between molar and mass units, type the formula or the molar mass.
- The table shows the same concentration in every other unit.
Frequently asked questions
How is ppm worked out?
As mg per liter, which is right for dilute solutions in water.
What does % (w/v) mean?
Grams per 100 mL, so 1% (w/v) is 10 g/L.
