Your Sun this morning

There were a few prominences that caught my eye. Seeing was not particularly good between 730am and 830am.

I have tried to put in the size of the Earth as approximate as I could and placed it on the black disc in image 2. Have I got my math below right for an approximation? Is there a better way to do this?

My Sun image is 420mm diameter on my big monitor.
Sun is 1,392,000km diameter.
1,392,000km divided by 420mm = 3314km per mm.
Earth is 12756km at Equator.
12756km dived by 3314km = 3.85mm size of Earth.

Thanks for looking.
Peter
