unit conversion application wanted

[keevill]

Looking for unit conversion application preferably via Cydia or Icy - NOT itunes.
Any recommendations ?

I've heard of conversion apps causing excess battery usage because they always need to update exchange rates. Can't you get your answers with a Google search, for example?

YMMV

they of course only update when you tell them to do so.
I use ConvertBot from the Appstore and it has a setting if it should update automatically (with schedule) or manually. Of course it only updates when you launch the application.

It can not run in the Background by itself to get updates, as it is an official Appstore app.
