Unit History
About light years
A light-year, though not part of the SI system, is a common astronomical unit used to express vast distances in space. It came into broader usage after scientific measurement of the speed of light in the 19th century. Scientists and educators often use light-years to help illustrate the immense scales between celestial objects, offering a more tangible sense of distances in the universe.
About feet
The foot is an ancient unit of measurement found in multiple civilizations, although it eventually became standardized at exactly 0.3048 meters. It persists in everyday usage in the United States and in some technical contexts (like altitude in aviation). Its convenience lies in its simplicity for measuring room dimensions or personal height.
