What is a femtometer used for?

A femtometer measures extremely small lengths typically used for atomic nuclei sizes and nuclear interactions.

How long is one hand in inches?

One hand is exactly equal to 4 inches, traditionally based on the breadth of a human hand.

Why convert femtometers to hands?

Converting femtometers to hands helps illustrate the huge difference between nuclear-scale lengths and everyday measurements like horse height.
