Historical origin

The yard derives its name from the word for a straight branch or rod, although the precise origin of the measure is not definitely known. Some believe it derived from the double cubit, or that it originated from cubic measure, others from its near equivalents, like the length of a stride or pace. For the multi-touch interface see CUBIT (multi-touch. For the unit of information see Qubit. One postulate was that the yard was derived from the girth of a person's waist, while another claim held that the measure was invented by Henry I of England as being the distance between the tip of his nose and the end of his thumb. Henry I (c 1068/1069 – 1 December 1135) was the fourth son of William I the Conqueror, the first King of England after the Norman These are believed to be more likely standardising events than a random invention of the measure. ^[2]

In currency and financial market usage, "yard" derives from "milliard", a now rarely used term for 1,000,000,000. Milliard is a French -derived word meaning the number 1000000000 (109 one thousand million SI prefix Giga)
