Natural number
100,000 (one hundred thousand ) is thenatural number following99,999 and preceding 100,001. In scientific notation, it is written as 105 .
InBangladesh ,India ,Pakistan andSouth Asia , one hundred thousand is called alakh , and is written as1,00,000 . TheThai ,Lao ,Khmer andVietnamese languages also have separate words for this number:แสน ,ແສນ ,សែន (allsaen ), andức respectively. TheMalagasy word ishetsy .[ 1]
Inthe Netherlands , a 'ton ' is a colloquialism for a denomination of 100.000 monetary units. In theguilders period a ton would denote 100.000 guilders. With the introduction of the euro, a ton would come to mean 100.000 euros. The usage is mostly limited to the financial sphere and the buying and selling of houses. It is not used in official settings because of the ambiguity with commonly usedmetric tonne . While usage is common in the Netherlands, it sees almost no use inBelgium .[citation needed ]
InCyrillic numerals , it is known as the legion (легион ): or .
Inastronomy ,100,000 metres ,100 kilometres , or100 km (62 miles) is thealtitude at which theFédération Aéronautique Internationale (FAI) definesspaceflight to begin.
Inpaleoclimatology , the100,000-year problem is a mismatch between the temperature record and the modeledincoming solar radiation .
In theIrish language ,céad míle fáilte (pronounced [ˌceːd̪ˠ ˈmʲiːlʲə ˈfˠaːl̠ʲtʲə] ) is a popular greeting meaning "a hundred thousand welcomes".
