Unit Definition (libra [ancient Rome])
The libra [ancient Rome] is a traditional unit of weight. The libra was the Roman unit from which the English pound is descended; the symbol "lb" for the pound comes from this unit. The Roman libra contained only 12 unciae (ounces) and was about 0.722 English pound. The word "libra" is sometimes used now for the kilogram, a much larger unit.

Unit Definition (technische mass einheit (TME))
The technische mass einheit (TME) is a German abbreviation for Technische Mass Einheit (engineering mass unit). One TME is the mass accelerated at 1 m/s2 by a force of 1 kgf. One TME is equal to 9.80665 kilograms or 21.6200 pounds. This unit is sometimes called the metric slug in English, since the slug is defined in a similar way in the English system.
