What is a Astronomical Unit and a Inch?
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 inch is a unit of length in the British imperial and United States customary systems of measurement. It is defined as exactly 1/12 of a foot or 2.54 centimeters.
Note: The Astronomical Unit is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Inch belongs to the imperial/US customary system.
History of the Astronomical Unit and Inch
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 inch has ancient origins, historically related to the width of a thumb or the length of three barleycorns laid end-to-end. Its definition was standardized internationally in 1959 based on the metric system (1 inch = 2.54 cm exactly).
Common Uses for astronomical units and inches

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 Inch (in)
How many inches are in a foot?
There are exactly 12 inches (in) in 1 foot (ft).
How many centimeters are in an inch?
There are exactly 2.54 centimeters (cm) in 1 inch (in).
Where is the inch primarily used?
The inch is the standard unit for many everyday length measurements in the United States. It is also used to some extent in Canada and the UK, though metric is more common officially.
