What is a Stone in Weight Measurement?

The stone (st) is a unit of measure equal to 14 pounds (lb) avoirdupois, or 6.3503 kilograms (kg). The plural of stone is also stone.

The stone measurement remains widely used in Britain, Australia, and Ireland for measuring human body weight. In the U.K. people may be said to weigh, e.g., "11 stone 4" (11 stones and 4 pounds), rather than "72 kilograms", or "158 pounds" as in the U.S.

Many scales today provide a "change weight display" setting that you can select to display either kilograms, pounds, or stone/pounds.

Countries Using Imperial and Metric Systems

In Australia, New Zealand, and increasingly so in Canada, the metric system (kilograms) has replaced the measurement of stone and pounds since the 1960's-70's.

The stone unit of measurement is still used in Great Britain, Ireland, and by some people in Australia for measuring human body weight - as it will probably take a generation or more for populations to fully convert to the metric system, ie. kilograms instead of stones or pounds. People in those countries, who still use the stone unit of measurement, are said to weigh, e.g., 11 stone 4 (11 stone - 4 pounds), which equals approx. 72 kilograms or 158 pounds.

The United States still uses the older Imperial system, e.g. pounds as body weight measurement, however, U.S. law has indicated the metric system to be preferred, but not the only one allowed - compliance is totally voluntary - some people and industries do so fully, some do not at all, and most are a mix.

The imperial (avoirdupois, or international) pound is officially defined as 453.59237 grams.
