| The word 'inch' derives from the Latin 'uncia' meaning one-twelfth, as it represented 1/12 of a Roman foot. In Scotland around 1150, King David I defined the inch as the width of a man's thumb at the base of the nail. To ensure consistency, this measurement was calculated by averaging the thumb widths of three men - one small, one medium, and one large. |
