Translation of ohm in Spanish

I would like to give you a proofreader's project. Proof reading sample sentences that were entered into the dictionary by our users. It is a very tough project and needs a lot of discipline and patience.
I would also need to know whether pricing can be different, because otherwise that amount would be too high. Some of the translations are not accurate at all and would also need corrections so that the dictionary displays only correct words.
I now live in Spain. I have moved too 2 years ago. I have finished my studies and in February I'm going to high school. I have not spoken German for a long time, actually since I was a kid.
