Convert from zentner [Germany] to technische mass einheit (TME)

Unit Definition (zentner [Germany])
The zentner is a traditional German unit of weight or mass, comparable to the traditional quintal and to the English hundredweight. Similar units were used in Scandinavia. Originally the zentner was equal to 100 pfund, or German pounds. 100 pfund varied from 110 to as much as 120 pounds avoirdupois (49.9-54.4 kilograms), depending on the market. After the introduction of the metric system in Germany, the zentner was redefined to equal to exactly 50 kilograms, which is about 110.231 pounds. In English, the zentner is commonly spelled centner.

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.
