What is a kilometer used for?

A kilometer is a unit of length equal to 1,000 metres, commonly used to measure distances on roads, maps, and in daily activities.

What does an attometer measure?

An attometer, equal to 10^-18 metres, is used to describe extremely small distances in particle physics and high-energy scientific studies.

Why convert kilometers to attometers?

Converting kilometers to attometers helps relate large-scale distances to subatomic scales, useful in advanced scientific modeling and high-energy physics.
