We haven't had a guvinmint willing to fully embrace metric (km's instead of miles, per se) since our half-arsed embrace of it in the 1970's when we dropped £sd for £p's, despite the fact that kids for yonks have grown up with the metric system. They are all 1m something (between 1.50 and 1.90 for the most part) and weigh in at somewhere in the 60-80 kg range which is 9.5 - 12.5 stone to us Neanderthals. A few might be a tad over that range or beyond the mythical range of the BMI scale.
