How to say 2.5 億 in English??

two hundred and fifty million OR
o.25 billion

2007-11-15 11:33:32 補充：
1 billion = 1000 million = 10億

be careful:

billion in British English = one million million

but

in American English = one thousand million

so what exactly you are asking?

2.5 億 = 250,000,000 = 250 million or 0.25 billion (1 billion = 1,000,000,000)

million 係百萬

跟住係　ｂｉｌｌｉｏｎ　，　十億

２．５　億　即係　

２５０　ｍｉｌｌｉｏｎ

即

two hundreds and fifty millions

2.5 億
= two hundred fifty million

two and a half billion
