Olympic sized swimming pools
It is now becoming more of a unit of measurement than metres etc. In the past 48 hours one radio station described a heath fire as covering an AREA the size of 130 swimming pools, and this morning $ky News are reporting the levels of radiation rising in water around Fukashima, the amount of water being enough to fill 48 Olympic sized swimming pools
Oh, and as an add-on, they reported another fire covered 1,000 sq m and it took 8 hours to put it out. It turns out it was one sq km. Thick bastards
