tables on this site are taken from;
SMALLER LATIN-ENGLISH DICTIONARY
While more recent scholarship may have updated some of Mr Smith's assumptions, I know of no web resources that catalogue as comprehensively the minutae of Roman Classical measurement.
The tables are generally unaltered except for my own conversions from Imperial to metric. Roods, perches and avoirdupois grains are very much a foreign language to many today. For any scholars who wish to see the originals, email me and I'll send scanned images.
