This calculator allows you to convert from Fermi to Angstrom and in a reverse direction. To convert from Fermi to Angstrom, enter the amount of Fermi into the first input and to convert from Angstrom to Fermi, enter the amount of Angstrom into the second input.
Every 1 Fermi = 1.0E-5 Angstrom
and so, 4 Fermi = 4 multiplied by 1.0E-5 = 4.0E-5 Angstrom.
Fermi
What is the fermi?
A fermi is equivalent to a femtometer. It is the older non–SI measurement unit of length. The femtometer is a unit of length. It can be abbreviated as fm. It is used in the SI system of units. It equals 1×10−15 meters. It is used mainly in nuclear physics.
Angstrom
What is angstrom?
Angstrom, named after the Swedish physicist Anders Jonas Angstrom, is a vert tiny length unit. It equals 10−10 meter.
Angstrom is not considered as a part of the SI system of units but it is defined in the metric system.
Now, let's mention some applications of Angstrom:
measurement of wavelengths of light.
express sizes of atoms, molecules and microscopic biological structures
