I didn't know the focusing distance was calculated from the sensor. How do I calculate the focusing distance then?

Unfortunately, different methods of calculating DoF use different ways to measure the distance.

The DoF calculator that you used (dofmaster.com) says the following in its FAQ:

What Gerry says (measure from the sensor position) is the traditional method for measuring the distance because it is easy to do, but the equations for DoF then become more complicated.  There is usually a mark on the top plate of the camera to indicate the sensor position and you measure from there.
