But, I want to be sure it is the best for the money. I have bought software in the past that were dogs and it is always good to get input from other actual users of the software before the purchase.
The kind of converter I'm looking for is for weights, distance, volume, etc. from one type measurement to another, like maybe CC to CI or Farenheit to Celcius, etc.
The last converter I got was freeware and it was an old DOS program that isn't even mouse-aware. That's how old it is and it still works great in all versions of Windows I've had since. (I have to turn my mouse up-side-down or it goes crazy, though.)
