The distance is in pixels. The actual physical distance will depend on the distance of your camera to the object being measured which will depend on your specific setup.

The easiest way you determine this is to put a ruler in front of the camera at the distance you want to measure and then measure a known distance. Given the number of pixels the distance is and a known distance in cm, mm, or whatever you use you know have a scaling factor that you can multiply the number of pixels by to get the actual size.

Note that this factor will change depending on the distance to the object ... so that HAS to stay the same.
