Hi there...
I know that this may sound a little basic, but does anyone have or know of a website where I can obtain
a (freeware) little program that will convert thou to millimetres & visa versa ?
 
For the past few years I have found it simple enough to pick up the digital verniers and use them
but these days too many people keep borrowing them.
 
As my math was never too good I find it easier to pick them up rather than a calculator.
