Inches to Astronomical Units

Inch

An inch (in) is a standard unit of length in the imperial system, widely used in the United States, Canada, and the United Kingdom. It is defined as 1/12 of a foot or exactly 25.4 millimeters in the metric system. Inches are commonly used to measure screen sizes, clothing, paper dimensions, and everyday household items.

Because many industries still rely on imperial measurements, converting inches to centimeters, feet, or other units is often necessary. A reliable converter helps ensure accuracy, especially when handling technical specifications.

Astronomical Unit

An astronomical unit (AU) is a standard space measurement based on the distance from the Earth to the Sun—about 149.6 million kilometers or 93 million miles. It helps describe solar system distances in practical numbers rather than extremely large values.

Astronomers use AU values to measure orbits of planets, asteroids, and comets relative to Earth.
