Euric wrote Is Big Ben's clock face really an exact 100 metres above the ground?
Big Ben is the bell that strikes the hours. The clock is Westminster Clock. (Even the tourist books, published in England, get that one wrong.) As to the altitude of the clock faces (four of them), I don't know the answer to that one. Bill Potts, CMS Roseville, CA http://metric1.org [SI Navigator]
