I often see numbers written like this: 19.456 thousand or this: 19,456 thousand. Neither is correct in English, and both may cause confusion.

我經?？吹接腥诉@么用英語來寫數字：19.456千，或者19,456千。這兩種寫法都不對，而且會引起誤會。

In English we do not mix numerals and words unless we are using the words “million”, “billion”, “trillion” etc. So, it is wrong to write, e.g., 24 thousand; instead you should write 24,000 or twenty-four thousand.

在英語中，除了表示“百萬”，“十億”，“萬億”等詞外，數字和單詞是不能混用的。比如，你如果寫24千，那就是錯的，你應該寫成24,000 或者twenty-four thousand（用數字，就全部用數字；用單詞，就全部用單詞；不能夾雜著用）。

19.456 thousand or 19,456 thousand should therefore be written in English in either of the following ways:

所以，19.456千，或者19,456千應該按照下面這樣的方式寫才對：

19,456,000 or 19.456 million (read as “nineteen million, four hundred and fifty-six thousand” or “nineteen point four-five-six million”)

19,456,000 或者19.456 million（讀作，一千九百四十五萬六千）。
