In stones, 14 stone is 88.9 kg, so 90 kg is 1.1 kg over that mark. UK and Irish scales usually display the stone figure and the leftover pounds separately rather than as a decimal.
Ninety kilograms is a judo weight class and a common boundary for load-bearing consumer equipment. It is also the point at which the gap between the metric and imperial figures becomes large in absolute terms — approaching 200 lb — so a rounding error that was trivial at 50 kg starts to be worth avoiding.
