  2. Other countries like England and other Germanic-speaking countries of northern Europe formerly used numerous standardized "stones" for trading purposes, with their values ranging from 5 to 40 local pounds (approximately 3 to 15 kg) depending on the geographic location and objects weighed. However, With the arrival of metrication in the mid-19th century, Europe's various "stones" were replaced by or adapted to the kilogram.

  3. During ancient times, a Biblical law was against the carrying of "diverse weights, a large and a small. The law carried a statement that "no one shall carry a stone and a stone, neither a large nor a small". 

  4. In the Jewish world, there was no standardized "stone"; however, in Roman times, stone weights were created to multiples of the Roman pound. Such weights constantly changed in quality, like, the Yale Medical Library held between 10 to50-pounds and these were stated examples of polished serpentine, while a 40-pound was an example at the Eschborn Museum made of sandstone.
