Solution concentration

C = m / V

Solute mass (mg)Final solution volume (mL)Enter all values to calculate.

Use the measured final solution volume, not the volume of solvent added.

Dilution

C₁V₁ = C₂V₂

Stock concentration (mg/mL)Target concentration (mg/mL)Final solution volume (mL)Enter all values to calculate.

Target concentration must not exceed stock concentration. Assumes additive volumes and unchanged solute; confirm solvent compatibility and the final measured volume independently.

Unit conversion

1 mg = 1000 µg · 1 mL = 1000 µL

ValueConversionEnter all values to calculate.

Results use up to 8 significant digits. Precision depends on your measurements.
