This calculator converts percentage by weight or parts by weight to percentage by volume and also parts by volume. The Density or Specific Gravity of each indivdual component is required. This calculator is useful when mixing components by volume is preferred to mixing by weight. Density can be in any units provided the units are the same for all components. Specific Gravity is unitless so it can be used anytime. Please do not use a mix of density and Specific Gravity. Please use the "Add Rows" button if there are more than two components.
