But it is 1 chain, (22 yards), surely? And you admitted that is not 20m when laid out properly. The laws of cricket have not changed (even if they give a metric equivalent) just because we might have joined the EU!! I have no objection to using a metric measure to do it but you have to use a non-integer value - and do the conversion. Not very elegant. So if tape measures with joint metric/imperial markings are available - and they are - why not use the correct measure in the first place? As to the definition of the inch it works both ways - why have 25.4 subdivisions of an arbitrary length to equal one inch. Just use an inch - it's no less valid and the yard/metre can both be defined in exactly the same way as so-and-so many wavelengths of Kr86 light. As I said, it's just that the internal standards conversions in the 'metric' system are easier. Just nit-picking, really. I use both systems happily as, I suspect, most people of my age do, depending on circumstance.

Paul, a cricket pitch is 20 m. Sure when the curator draws the lines it is 12cm longer, (and I guarantee s/he uses a metric measure) but when we pace it out for backyard cricket - its 20 m. Also my American friends, all your imperial measurements are DEFINED in terms of metric. eg your inch is 25.4 mm exactly. By definition. It has been estimated you could save a trillion dollars a year in your economy by converting - which you will ultimately do. I just hope it is in my lifetime.
