But when using a tape measure surely most people use the top scale for accurate measurement ? Same as using a ruler when measuring a line on a piece of paper. So why are the inches always still on top ?
O.K. so why not buy a metric only tape measure instead ? Except that all the metric only tapes only have the scale on only the one edge - again the bottom edge which is most inconvenient. They compensate for not giving the you the imperial scale at the top by giving you bigger numbers. Basically the metric only tape is the combination tape with the imperial scale removed from the top edge of the printing plate.
Gold medal for prize chumps must go to B&Q. They do a nice two sided metre rule in aluminium with the two scales on the two edges metric and inches. Except the inches are at the top on both sides, they're identical.
Full marks to Wickes - theirs seem identical in every other respect including price except the metric is on the top edge on one side.
Its just I've never noticed this before and was looking to replace some steel tapes.
