Are you confused? We were. Years of calculations out of the window, mental arithmetic and judgement of distance, weight and volume up the spout. Away went inches, yards, fathoms, furlongs, but confusingly we kept ounces, pounds and stones, for a while. Why did we have a 12 times table anyway? What was the relevance of 144, and why do we still use miles?
