The numbering system in Chinese is based on four-digit numbers. It contains a strong uniformity as shown in the diagram below.
亿: hundred million 千万: ten million 百万: million
十万: hundred thousand 万: ten thousand 千:thousand
百: hundred 十: ten 个: one
(1) When a large number contains a zero in between other numbers, no matter how many zeros it has, we only read one of them.
For example: The English equivalent of the Chinese for 108 should be read as “一百零八 (yì bǎi líng bā) one hundred and eight.”
The English equivalent of the Chinese for 320,045 should be read as “三十二万零四十五 (sānshíèr wàn líng sì shí wǔ) three hundred twenty thousand and forty-five.”
The English equivalent of the Chinese for 69,320,001 should be read as “六千九百三十二万零一 (liùqiān jiǔbǎi sānshíèr wàn líng yī) sixty-nine million three hundred twenty thousand and one.”
(2). "二" and "两" both mean "two." We use both of them when we count numbers.
Ⅰ. When "2" comes before "十," we only use "二." For example: "二十 twenty."
Ⅱ. When placed in the middle of numbers such as “hundred,” “thousand,” “ten thousand" and "hundred million," we generally use "二."
For example:
三千二百万 (sānqiān liǎngbǎi wàn) Thirty-two million.
四千二百三十万(sìqiān liǎngbǎi sānshí wàn)
Forty-two million and three thousand
Ⅲ. When "2" comes in front of a three digit number, we can use both "两" and "二." For example: Two hundred and thirty.
When "2" is placed ahead of four, five and six digit figures, we generally use "两."
For example:
二十 (érshí) (20) twenty
二（两）百五十六 (èr/liǎngbǎi wǔshíliù) (256)
two hundred and fifty-six
二（两）百万 (ér/liǎngbǎi wàn) (2,000,000)
two million
两千六百四十七 (liǎngqiān liùbǎi sìshíqi) (2,647)
two thousand six hundred and forty-seven
两万八千九百一十六 (liǎngwàn bāqiān jiǔbǎi yīshíliù) (28916)
twenty-eight thousand nine hundred and sixteen
两千二百万 (liǎngqiān èrbǎi wàn) (22,000,000)
twenty-two million
两亿二千万 (liǎngyì liǎngqiān wàn) (220,000,000)
two hundred and twenty million
(3) Decimals
In Chinese, We often read decimal points as “点 point.” As for the numbers after the decimal point, we just read them one by one. For the numbers before the decimal point, we follow the rules of numeration.
For example:
0.6 should be read “零点六 (líng diǎn liù) zero point six.”
3.1415 should be read “三点一四一五 (sān diǎn yī sì yī wǔ) three point one four one five.”
356.42 should be read “三百五十六点四二 (sānbǎi wǔshí liù diǎn sì èr) three hundred and fifty-six point four two.”
