I hate being pedantic but why do all the news reports about wildfires seem to use the well known measurement of football pitches. Did I waste time learning square metres, kilometres or even sq miles? Also I've heard 'an area of 5km' quoted on news reports. Isn't it 5 sq km or a length of 5km? Sorry, I'll shut up now.
@Seb321 Maybe they mean to scoop Australia out and mold it into a ball.... @kibcol1049
