Fermis to Kilometers: the quick answer
1 fm = 1 × 10⁻¹⁸ km
1 fermi equals 1 × 10⁻¹⁸ kilometers
To convert fermis to kilometers, multiply the value by 1 × 10⁻¹⁸. To go the other way, multiply kilometers by 1 × 10¹⁸ to get fermis.
To convert fermis to kilometers, multiply the value by 1 × 10⁻¹⁸. To go the other way, multiply kilometers by 1 × 10¹⁸ to get fermis.

Fermi (fm). A fermi (femtometer) is 10⁻¹⁵ meters, roughly the size of a proton, used in nuclear physics.
Kilometer (km). A kilometer is 1,000 meters and the standard unit for road distances in most countries, including India.
There are 1 × 10⁻¹⁸ kilometers in one fermi.
Multiply the number of fermis by 1 × 10⁻¹⁸. For example, 10 fermis equal 1 × 10⁻¹⁷ kilometers.
One kilometer equals 1 × 10¹⁸ fermis.
1 × 10⁻¹⁵ kilometers. Other common values: 100 fermis = 1 × 10⁻¹⁶ kilometers and 10,000 fermis = 1 × 10⁻¹⁴ kilometers.
