The yard was measured from the tip of the nose to the tip of the fingers of which king?

Answer 1

In his Chronicles William of Malmesbury (1095 – 1143?) tells how the “false yard” was corrected by referring it to the length of King Henry I's arm. The story is not just a legend–William's descriptions of contemporary events are reliable–but William does not say this was the origin of the yard; it existed before Henry I was born. The yard was in the keeping of the guilds that dealt in cloth.

Answer 2

Henry I of England
