The stone remains widely used in the United Kingdom 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 and in Canada.

Stoney's set of base units is similar to the one used in Planck units, proposed independently by Planck thirty years later, in which Planck normalized the Planck constant [a] in place of the elementary charge. [8] Planck units are more commonly used than Stoney units in modern physics, especially for quantum gravity (including string theory ...
The weighing stone was uncovered in an archaeological context from Second Dynasty, in the so-called "labyrinth" building, it bears the inscription of the "friendly is the heart of Horus, director" (of the installation) "Hemsemenib". The inscribed value is of 3 deben, representing a unit of 29 grams (1.0 oz), likely the earliest copper deben. [2]
Today only the stone continues in customary use for measuring personal body weight. The present stone is 14 pounds (~6.35 kg), but an earlier unit appears to have been 16 pounds (~7.25 kg). The other units were multiples of 2, 8, and 160 times the stone, or 28, 112, and 2240 pounds (~12.7 kg, 50.8 kg, 1016 kg), respectively.
The Israelite system of powder/liquid volume measurements corresponds exactly with the Babylonian system. Unlike the Egyptian system, which has units for multiples of 1, 10, 20, 40, 80, and 160 of the base unit, the Babylonian system is founded on multiples of 6 and 10, namely units of 1, 12, 24, 60, 72 (60 plus 12), 120, and 720.

The slug is a derived unit of mass in a weight-based system of measures, most notably within the British Imperial measurement system and the United States customary measures system. Systems of measure either define mass and derive a force unit or define a base force and derive a mass unit [ 1 ] (cf. poundal , a derived unit of force in a mass ...
The quintal or centner is a historical unit of mass in many countries which is usually defined as 100 base units, ... for the weight from ... (8 stone or 112 pounds ...
Scottish or Scots units of measurement are the weights and measures peculiar to Scotland which were nominally replaced by English units in 1685 but continued to be used in unofficial contexts until at least the late 18th century. [citation needed] The system was based on the ell , stone , and boll and firlot .
