What is the difference between femtometer and fermi?

There is no difference in length value; both represent the same scale of 10^-15 meters but the units are used differently depending on the scientific context.

Why convert femtometer to fermi if they are the same length?

Converting to fermi helps standardize measurements in nuclear physics where the fermi unit is commonly used, improving clarity and communication.

No, fermi is a non-SI unit, which can limit its use in some international metrology standards.
