What is a femtometer used to measure?

A femtometer measures extremely small distances typical in nuclear and particle physics, such as atomic nucleus sizes and subnuclear interactions.

Why convert femtometers to micrometers?

Converting femtometers to micrometers helps relate atomic- and nuclear-scale lengths to more familiar microscale dimensions used in biological and engineering measurements.

What is the conversion rate from femtometers to micrometers?

The conversion rate is 1 femtometer equals 1 × 10⁻⁹ micrometers.
