Astronomical Unit to Centimeter Converter

About this conversion

The astronomical unit (au) is a unit of length in the astronomical, commonly used for distances between planets and orbital radius of planets. The centimeter (cm) belongs to the metric (SI) and is typically found in measurements related to clothing and shoe sizes and human height and body measurements. By definition, one astronomical unit is approximately 149,597,870.7 km — the mean distance from Earth to the Sun. One centimeter is one hundredth of a meter (0.01 m). The conversion factor between these two units is 14959787070000: multiplying any value in au by this number gives the equivalent in cm. For example, 10 au equals 149597870700000.0000 cm. Going the other direction, 1 cm equals 0 au. The centimeter has been part of the metric system since its adoption in France in the late 18th century.
