whats 1/4ww mean on a socket?

ive been given a few imperial sockets and found one that has 1/4ww on it. it is of a greater diameter than 1/4 inch, more like half inch! its got me baffled! just wondered if anyone could shed any light!
cheers

witworth?

it means 1/4 inch Whitworth.

old imperial measirement called whitworth. If I remember right 1/4 whit is the right size for a battery terminal.

quarter inch whitworth (thread size), I would guess.

funny how all us old geezers knew that!
