To convert inches to fermis, multiply the value by 25,400,000,000,000. To go the other way, multiply fermis by 3.93701 × 10⁻¹⁴ to get inches.

Inch (in). The inch is an imperial and US customary unit equal to exactly 25.4 millimeters, used for screen sizes, pipes and tyres.
Fermi (fm). A fermi (femtometer) is 10⁻¹⁵ meters, roughly the size of a proton, used in nuclear physics.
There are 25,400,000,000,000 fermis in one inch.
Multiply the number of inches by 25,400,000,000,000. For example, 10 inches equal 254,000,000,000,000 fermis.
One fermi equals 3.93701 × 10⁻¹⁴ inches.
304,800,000,000,000 fermis. Other common values: 5 inches = 127,000,000,000,000 fermis and 100 inches = 2.54 × 10¹⁵ fermis.
