How to convert chains to fermis

1 chain is equal to 2.01168 × 10¹⁶ fermis, and 1 fermi is equal to 4.970969538 × 10⁻¹⁷ chains. To convert, multiply by the conversion factor:

fermis = chains × 2.01168 × 10¹⁶
fermis = chains ÷ 4.970969538 × 10⁻¹⁷

Example: convert 1 ch to fm: 1 × 2.01168 × 10¹⁶ = 2.01168 × 10¹⁶ fm.

About the chain

Gunter's chain is 66 feet (20.1168 m), equal to 100 links or 4 rods. A cricket pitch is one chain long, and an acre is 10 square chains.

Symbol: ch · 1 ch = 20.1168 m · Category: Imperial & US customary

About the fermi

The fermi is the traditional name in nuclear physics for the femtometer (10⁻¹⁵ m), named after physicist Enrico Fermi.

Symbol: fm · 1 fm = 1 × 10⁻¹⁵ m · Category: Metric (SI)

Frequently asked questions

How many fermis are in a chain?

There are 2.01168 × 10¹⁶ fermis in 1 chain (ch).
