Ancient Roman

Roman length units were very well defined. The value of the base unit pes (foot) was discovered by John Greaves in 1639 after he made a lot of measurements in the ruins of Rome. Since then we know that the value of one pes was between 0.967 and 0.986 English feet. An accepted modern value is 296 mm. For most Roman units below we give an English equivalent in parentheses.
