Yup...

&h400's = 1024.

There's really no reason. Hex is easier to read and mentally process if
you're going to end up breaking the value up into numerical "words".
Each letter represents a nibble of data (4 bits). 2 letters per byte (8
bits) and so on.
fwiw, If you fire up Windows Calculator and select the 'View/Scientific'
menu, you'll have a way to calculate hex/binary/etc.
