Examples of usage

Mass Percentage
The mass fraction is also known as the mass percentage, mass per cent, percentage by mass, or percentage by weight when expressed in the percentage. It is abbreviated mass % or wt %.

“Mass fraction can also be expressed, with a denominator of 100, as percentage by mass (in commercial contexts often called percentage by weight, abbreviated wt%; see mass versus weight). It is one way of expressing the composition of a mixture in a dimensionless size; mole fraction (percentage by moles, mol%) and volume fraction (percentage by volume, vol%) are others.”
