While Bob & Bob comment that units on a cert may be stated in metric or imperial, I am suggesting that elevations and splits be submitted on certs in meters, as we (Vice-chairs and Gene) do the math to check the figures. If we have to convert from feet to meters to do the math, that adds time.
While I hear Bob's point of keeping the original info a little further into the process, I would ask "why does it matter, if it must be changed by the end, anyway?". I would rather see the conversion done earlier in the process (even by the measurer - now, don't get me going on 'measurers may make a mistake'! That's a lazy answer. We are all capable of doing the math. Even one-off measurers can be expected to do the math - we have all conversions in the Manual!), as it saves time as it moves up the chain. Gene sees every cert issued, and checks the math. Please, Paul, don't make Gene do the conversions while he is entering data into the database.
I convert all to metric, so Gene doesn't have to. I don't feel he should bear the burden of converting cert units. Just my (strong) opinion.
