Convert hectometer to attometer
Please provide values below to convert hectometer [hm] to attometer [am], or Convert attometer to hectometer.
1 hm = 1.0000e+20 am. To convert hectometer to attometer, multiply the value by 1.0000e+20; to go the other way, divide by it (1 am = 1.0000e-20 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 = 1.0000e+20 am
- 1 am = 1.0000e-20 hm
- 10 hm = 1.0000e+21 am
- 100 hm = 1.0000e+22 am
How to Convert Hectometer to Attometer
1 hm = 1e+20 am
Example: convert 15 hm to am:
15 hm = 15 × 1e+20 am = 1.5e+21 am

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.
Attometer
An attometer is a unit of length in the metric system equal to 10^-18 meters.
History/Origin
The prefix "atto-" for 10^-18 was adopted by the CGPM (General Conference on Weights and Measures) in 1964.
Current Use
The attometer is used in high-energy physics to describe the scales relevant to quarks and leptons.
Frequently Asked Questions
What is 1 hectometer in attometer?
1 hectometer (hm) = 1.0000e+20 attometer (am).
How do you convert hectometer to attometer?
Multiply the hectometer value by 1.0000e+20. For example, 25 hm × 1.0000e+20 = 2.5000e+21 am.
