Quick Reference

1 Fermi = 2.250e-14 U

1 U = 44450000000000.00 Fermi

Fermi to U Conversion Formula

To convert Fermi to U, multiply by 2.250e-14.

U = Fermi × 2.250e-14

Fermi = U × 44450000000000.00

To convert U back to Fermi, divide by 2.250e-14 (or multiply by 44450000000000.00).

About These Units

About Fermi

The Fermi was a metric unit of distance formerly used in atomic physics. One Fermi equals 10e-15 meter, or 1 femtometer. The unit was named after Enrico Fermi (1901-1954), the Italian-American physicist who built the first nuclear reactor.

About U

The U is a unit of distance used to measure the height of the standard racks in which audio, video, or computer components are mounted. 1U is equal to 1.75 inches (44.45 millimeters), so that, for example, a 2U component is 3.5 inches high, and a 22U rack houses a stack of components 38.5 inches high.
