10000 (ten thousand) is the natural number following 9999 and preceding 10001
Many languages have a specific word for this number: in Ancient Greek it is μύριοι (related to the word myriad in English), in Aramaic ܪܒܘܬܐ, in Hebrew רבבה (revava), in Chinese 萬/万 (Mandarin wàn, Cantonese maan6), in Japanese 万/萬 [man], in Korean 万/만/萬 [man], and in Thai หมื่น [meun]. It is often used to mean an indefinite very large number.[1]
The Greek root was used in the earlier versions of the metric system in the form myria-.
The number 10000 can also be written 10,000 (UK and US), 10.000 (Europe mainland), 10 000 (transition metric), or 10•000 (with the dot raised to the middle of the zeroes; metric).
