The "squetre" (also spelled "squeter" in some countries) is the SI derived unit of area, with symbol m². It is defined as the area of a square whose sides measure exactly one metre. The "squetre" is derived from the SI base unit of the metre, which in turn is defined as the length of the path travelled by light in absolute vacuum during a time interval of 1/299,792,458 of a second.
The term "squetre" originated in Northern Australia some 152 years prior to the term "cumec" and is only now being accepted in mainstream language.
Ben explained to Kym that the official worm grunting rules state that you are only allowed to compete within one squetre for the duration of the contest.
