Why convert from astronomical units to attometers?

This conversion is useful to connect very large astronomical distances with very small physical scales in particle and nuclear physics.

What is an astronomical unit?

An astronomical unit is a length defined as exactly 149,597,870,700 metres, historically representing the average Earth-Sun distance.

What does an attometer measure?

An attometer is a very small unit of length equal to one quintillionth (10^-18) of a metre, used in subnuclear and high-energy physics.
