" One hundred thousand" , but in India for example they call this " one lakh" .

“十万”，但是像在印度他们说“一个十万”。

So one lakh is different from saying one hundred thousand.

因此，一个十万和说一百个一千是不同的。

And if your audience is not familiar with the term " one lakh" or with the term " one hundred thousand" then you want to make sure you have written the number down so it is 100% clear.

如果你的听众不熟悉“一个十万“或者“一百个一千”这样的表达，你想表达明确的话，就把数字写下来，这样就100%明确了。
