Convert hectometer to astronomical unit
Please provide values below to convert hectometer [hm] to astronomical unit [AU, UA], or Convert astronomical unit to hectometer.
1 hm = 6.6846e-10 AU, UA. To convert hectometer to astronomical unit, multiply the value by 6.6846e-10; to go the other way, divide by it (1 AU, UA = 1495978707 hm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 hm = 6.6846e-10 AU, UA
- 1 AU, UA = 1495978707 hm
- 10 hm = 6.68458712227e-09 AU, UA

Hectometer
A hectometer is a unit of length in the metric system equal to 100 meters.
History/Origin
The prefix "hecto-" from the Greek "hekaton" meaning hundred, was part of the original metric system adopted in France in 1795.
Current Use
The hectometer is not a widely used unit of length in English-speaking countries. It is sometimes used in surveying and for marking distances on highways in some countries.
Astronomical Unit
The astronomical unit is a unit of length, now defined as exactly 149,597,870,700 meters. It is approximately the average distance between the Earth and the Sun.
History/Origin
Historically, the astronomical unit was the mean Earth-Sun distance. In 2012, the International Astronomical Union (IAU) redefined it as a fixed constant.
Current Use
The astronomical unit is used primarily for measuring distances within the Solar System or around other stars.
Frequently Asked Questions
What is 1 hectometer in astronomical unit?
1 hectometer (hm) = 6.6846e-10 astronomical unit (AU, UA).
How do you convert hectometer to astronomical unit?
Multiply the hectometer value by 6.6846e-10. For example, 25 hm × 6.6846e-10 = 1.67114678057e-08 AU, UA.
