    In everyday conversation, and in informal literature, it is common to see lengths measured in units of objects of which everyone knows the approximate width. Common examples are: Double-decker bus (9.5–11 meters in length) American football field (100 yards in length) Thickness of a human hair (around 80 micrometers)
