An amateur website appears to be widely acknowledged as having good data. The author originally used non-metric data but responded to requests to add metric (although he required that others did the actual conversions). He made a few mistakes in formatting the units and again responded to feedback. There are still a couple of errors but the guy has done very well so far, particularly considering that he has suggested that he is not in favour of metric. So if you give feedback, please be polite.
