"One trillion won"

Translation: 일조 원

[SvedishPlumber]

Is it necessary to put 일 before 조? When you say 10,000 you dont say 일만

[Ash-Fred]

Yes, all primary number units 억, 조, 경, 해, etc. need 일 but 만.

[SpoTify0]

천은요? You don't say 일천

[suhandiwiratama]

In hanja, you write it as:
일 --> 一
조 --> 兆
원 --> 元

조 here means trillion.

[JasonWong940585]

How's the pronunciation different from 위즈 * 원? I kept hearing the same thing

[SNSD_S0NEf0rever]

일조 means 1 billion, not 1 trillion. 일경 is one trillion.
