Convert hectometer to femtometer
Enter a value below to convert hectometer [hm] to femtometer [fm]. Reverse conversion: Convert femtometer to hectometer.
1 hm = 1.0000e+17 fm. To convert hectometer to femtometer, multiply the value by 1.0000e+17; to go the other way, divide by it (1 fm = 1.0000e-17 hm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Hectometer to Femtometer: Quick Reference
- 1 hm = 1.0000e+17 fm
- 1 fm = 1.0000e-17 hm
- 10 hm = 1.0000e+18 fm
- 100 hm = 1.0000e+19 fm
How to Convert Hectometer to Femtometer
1 hm = 1e+17 fm
Example: convert 15 hm to fm:
15 hm = 15 × 1e+17 fm = 1.5e+18 fm

Hectometer: Definition and Use
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.
Femtometer: Definition and Use
A femtometer is a unit of length in the metric system equal to 10^-15 meters. It is also known as a fermi.
History/Origin
The prefix "femto-" for 10^-15 was adopted by the CGPM (General Conference on Weights and Measures) in 1964. The unit is also named after the physicist Enrico Fermi.
Current Use
The femtometer is primarily used in nuclear physics to measure the size of atomic nuclei.
Hectometer to Femtometer: Frequently Asked Questions
What is 1 hectometer in femtometer?
1 hectometer (hm) = 1.0000e+17 femtometer (fm).
How do you convert hectometer to femtometer?
