DMcG I hear what you say. In reality many units of measurement contain elements of conflict. The French were not too impressed with 0Longitude going through Greenwich. In reality it should perhaps have gone through
Barrow in Lincolnshire where John Harrison first played with clocks. He constructed the first chronometer making accurate determination of longitude possible. Our calendar and week names are beset with heathen origins, but I doubt anyone really thinks about it anymore. Even Christmas has more heathen overtones than christianity, but it is still a hell of an excuse to party.
