Concentration Calculator

Solution concentration calculators convert between molarity (mol/L), mass concentration (g/L), and percent concentration (% w/v). Used in chemistry, biology, pharmacy, and food science

The calculator uses the standard published formula for concentration calc. Results are accurate to the precision of the inputs you provide. For financial, medical, or legal decisions, always verify with a qualified professional.

This calculator works with inches, percentages. You can enter values in the units shown — the calculator handles all conversions internally.

The core formula is: Molarity (M) = Moles of solute / Volume of solution (L). Each step in the calculation is shown so you can verify the result manually.
