IN response to your correspondent Jean Chilvers ('Dump these antiquated measurements', June 3), I suspect the reason for not changing the metric units on all road signs is one of cost.

When weights and measures were changed, suppliers of goods and commodities had to pay for their scales to be converted; there was no cost to the Government. Changing road signs would have to be met by the Government hence, the reluctance. Ralph Hooks,
