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.
Centimeter
A centimeter (cm) is a widely used unit of length in the metric system. It represents one hundredth of a meter, making it ideal for measuring small objects or precise distances. You'll commonly see the centimeter used in school projects, everyday measurements, clothing sizes, and household tools like rulers and tape measures.
The centimeter bridges the gap between millimeters and meters, offering accuracy without tiny decimals. When converting to or from other units—such as inches, where 1 inch equals 2.54 centimeters—an online unit converter ensures speed and precision.
