Contrary to popular belief, the Norman conquest of England had little effect on British weights and measures, other than to introduce one new unit: the bushel. William the Conqueror, in one of his first legislative acts, confirmed existing Anglo-Saxon measurement, a position which was consistent with Norman policy in dealing with occupied peoples. Another popular myth is that the Magna Carta of 1215 (specifically chapter 35) had a significant effect on English weights and measures, for this document only mentions one unit (the London Quarter) but does not define it.
