Ko ngā waeine arowhānui ngā waeine e tino whakamahia ana puta noa i te ao, pērā i ngā waeine ngahuru. Arā, ko te mita mō te roa, ko te karamu mō te papatipu me te taumaha, ko te rita mō te kītanga.
Standard units of measurement are those which are commonly used throughout the world, such as the metric units, namely the metre for length, the gram for mass and weight, and the litre for capacity.
