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.

Does really exist since 1996? In fact it's even older. We launched the first version of our online units converter in 1995. There was no JavaScript there and all conversions had to be done on server. The service was slow. A year later the technology allowed us to create an instant units conversion service that became the prototype of what you see now.
