In the guilders period a ton would denote 100.000 guilders. With the introduction of the euro, a ton would come to mean 100.000 euros. Usage is mostly limited to the financial sphere and to the buying and selling of houses. It is not used in official settings because of the ambiguity with the commonly used metric tonne. While usage is common in the Netherlands, it sees almost no use in Belgium.July 2024 In Cyrillic numerals, it is known as the legion (Cyrl легион): 30px or 25px.
