Effectively in the EU, a directive (85/1/EEC) definitively allows the use of "mm Hg for the measure of blood pressure and other body fluids". The directive indeed follows a recommendation of the World Health Organization. Strange enough, whilst millimeters are the "official" unit, the common language uses centimeters : a typical figure being "13 - 8", not 130 - 80. May be our body is not SI designed ? Louis
