Format distance tool label to centimeter.

Can anyone tell me how to format the text in distance tool's label to centimeter?
Thanks

The distance tool reports in pixels for a very good reason:
An image doesn't have *physical* distance by itself. Real-world distance is only applied after you answer this question:
"How big (in cm, for example) is each pixel in my image"?
This answer will be very different depending on the image. Take a picture of your house. How many cm in each pixel? Take a satellite picture of your neighbourhood. How many cm in each pixel?
What I suggest you do is determine the "scale" of your pixels, ie, that each pixel represents 0.1cm, then multiply that number by what the distance tool reports.
If this is posted as an asnwer, I'd vote for it.
