Millimoles per litre — mmol/L
Grams per litre — g/L
Milligrams per litre — mg/L
Percent w/v — %

The formula
g/L = mol/L × molar mass % w/v = g/L ÷ 10
Everything passes through grams per litre, so the molar mass is the only extra figure needed.
What to watch out for
Percent here is mass per volume. For mass per mass, use the mass percent calculator.
Frequently Asked Questions
How do I convert mol/L to g/L?
Multiply by the molar mass. 0.154 mol/L of sodium chloride is 9 g/L, or 0.9% w/v.
How do I convert mg/L to mol/L?
Divide by 1000 to get g/L, then by the molar mass.
