Percentage Solution Calculator
% = (solute / total) × 100
Calculate % w/v, % v/v and % w/w solutions in both directions.
Inputs
1% w/v = 1 g solute per 100 mL final solution
Calculation
Definition
1% w/v = 1 g solute per 100 mL final solution
Solute amount
solute = (% / 100) × total
solute = (5 / 100) × 100 mL
solute = 5 g
Inputs
- Percentage type
- % w/v
- Percentage
- 5 %
- Final volume
- 100 mL
Mass and volume percentages are not interconverted automatically. Converting between them requires an explicitly known density.
About this calculator
Percentage concentrations are defined relative to the final solution or mixture, not to the solvent alone.
- 1% w/v = 1 g solute per 100 mL final solution
- 1% v/v = 1 mL solute per 100 mL final solution
- 1% w/w = 1 g solute per 100 g final mixture
Mass and volume percentages are never converted into each other automatically. That conversion requires an explicitly known density of the solution or the solute, which this calculator does not assume.
