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 miles
The mile has historical roots stretching back to ancient Rome, where it was based on the term 'mille passus' (a thousand paces). Over centuries, it evolved in English-speaking regions and is still common in the United States and some other countries for expressing road distances. Despite global reliance on the metric system, the mile remains a staple in everyday usage in these regions.
