I have on my cell phone what is called "tools", and under that, there's a "converter" which converts wieght to milligrams, miles to kilometers, etc. Unfortunately, mine doesn't have other things on there. My suggestion, is to check with various cell phones there to see what is on them. My hopes for you is that you'll find what you're looking for. Another option, which I'm sure will work, is to "Google" it. For example: Google "currency converter", then what comes up is "universal currency converter"; click onto that. I did a test: $25.00 U.S. dollars is in China 157.712 CNY. I hope this helps you!!!

If you mean expressing a number in another language (English), compared to the same number in your own language (Chinese), then it happens to most of us learners. :) My advice is to stop writing the numbers in your own language, and even write out numerals as full words, especially in text. Try making calculations in your head, using only the second language. Just practise, practice, and then practise until you're used to it.

practise writing figures this way: 230000->230,000 instead of 230000->23,0000. and so on.

I don't believe there is a shortcut. Only that practice makes perfect. when I exercise, I always count in Chinese...:) 我不信有容易方法学习怎么数用英文，就越练习越提你的能力。

1 万 = 10，000 so you just put 4 zeros behind. 23 万 = 230,000 then just change the number into words.
