OK... at the risk of sounding dumb, are witworth wrenches just metric wrenches, or are they something special?

The BIG difference in Whitworth tools is that the sizes are measured as the length of one side of the bolthead instead of the distance across the centre of the head. It gets a bit confusing to switch between Whitworth and SAE tools because a 1/4 inch Whitworth spanner is nearly the same size, slightly bigger as best I can remember, as a 1/2 inch SAE wrench.
