Convert femtometer to chain
Please provide values below to convert femtometer [fm] to chain [ch], or Convert chain to femtometer.
1 fm = 4.9710e-17 ch. To convert femtometer to chain, multiply the value by 4.9710e-17; to go the other way, divide by it (1 ch = 2.0117e+16 fm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 fm = 4.9710e-17 ch
- 1 ch = 2.0117e+16 fm
- 10 fm = 4.9710e-16 ch
- 100 fm = 4.9710e-15 ch
How to Convert Femtometer to Chain
1 fm = 4.97096953789867e-17 ch
Example: convert 15 fm to ch:
15 fm = 15 × 4.97096953789867e-17 ch = 7.45645430684801e-16 ch

Femtometer
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.
Chain
A chain is a unit of length equal to 66 feet, or 22 yards.
History/Origin
The chain was developed by English surveyor Edmund Gunter in the early 17th century. It was designed to be a convenient length for surveying land.
Current Use
The chain is still used in some surveying applications and is the length of a cricket pitch.
