Siehe auch: kg/te fuel - what does the abbreviation "te" mean?

The Leonides have wondered about this before. Apparently, it's a "metric ton". See here: https://www.inchcalculator.com/convert/from-m...

The metric ton is an SI accepted unit for weight for use with the metric system. A metric ton is sometimes also referred to as a tonne. Metric tons can be abbreviated as t, and are also sometimes abbreviated as T, Te, or MT. For example, 1 metric ton can be written as 1 t, 1 T, 1 Te, or 1 MT.

OT: Manche Abk. kann man echt in die Te. treten!
