Word origin

平方 (heihō) is a Sino-Japanese compound formed from 平 (hei, "flat") and 方 (hō, "direction or side"), with the term recorded in Chinese mathematical usage before its use in Japanese.

Usage tips

  • 平方 (heihō) can refer to both the operation of multiplying a number by itself and the resulting value, so context determines whether it means squaring or a square.
