What is a Astronomical Unit and a Mile?
An astronomical unit is a unit of length roughly equal to the average distance between Earth and the Sun. It is defined as exactly 149,597,870,700 meters.
The mile, specifically the international statute mile, is a unit of length in the British imperial and United States customary systems. It is defined as exactly 5,280 feet, 1,760 yards, or approximately 1.609344 kilometers.
Note: The Astronomical Unit is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Mile belongs to the imperial/US customary system.
History of the Astronomical Unit and Mile
Historically used to measure distances within the Solar System, its value was refined over centuries through astronomical observations. The exact definition was adopted by the IAU in 2012.
The mile originated from the Roman "mille passus", meaning "thousand paces" (where a pace was two steps). Its length varied considerably until Queen Elizabeth I of England standardized it as 5,280 feet in 1593. The international mile agreement of 1959 confirmed its definition based on the metric system.
Common Uses for astronomical units and miles
Explore the typical applications for both Astronomical Unit (imperial/US) and Mile (imperial/US) to understand their common contexts.
Common Uses for astronomical units
- Measuring distances within the Solar System (e.g., planet orbits)
- Expressing distances to near-Earth objects
Common Uses for miles
- Geography & Travel (US/UK): Measuring geographic distances and road lengths in the US, UK, and some other countries.
- Transportation (US/UK): Road speed limits (miles per hour, mph) in the US and UK.
- Maritime & Aviation: Nautical and aviation use a related unit, the nautical mile (approx. 1.852 km).
- Athletics: Running events (e.g., the mile run).
Frequently Asked Questions
Questions About Astronomical Unit (AU)
Why use Astronomical Units instead of kilometers or miles?
Astronomical Units (AU) provide a more convenient scale for the vast distances within our solar system. Expressing interplanetary distances in km or miles results in extremely large and unwieldy numbers.
How many kilometers/miles is 1 AU?
1 Astronomical Unit (AU) is approximately 149.6 million kilometers or 93 million miles.
How long does it take light to travel 1 AU?
It takes sunlight approximately 8 minutes and 20 seconds to travel the distance of one Astronomical Unit from the Sun to the Earth.
About Mile (mi)
How many feet are in a mile?
There are exactly 5,280 feet (ft) in 1 mile (mi).
How many yards are in a mile?
There are exactly 1,760 yards (yd) in 1 mile (mi).
Is a mile longer or shorter than a kilometer?
A mile (approx. 1.609 km) is longer than a kilometer (1 km).
