The stone remains widely used in the UK and Ireland for human body weight: in those countries people may commonly be said to weigh, e.g., "11 stone 4" (11 stones and 4 pounds), rather than "72 kilograms" as in most of the other countries, or "158 pounds", the conventional way of expressing the same weight in the US. The correct plural form of "stone" in this context is "stone" (as in, "11 stone" or "12 stone 6 pounds"); in other contexts, the correct plural is "stones" (as in, "Please enter your weight in stones and pounds"). In Australia and New Zealand, metrication has almost entirely displaced stones and pounds since the 1970s.
