What is an astronomical unit (AU)?

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

Why convert astronomical units to nanometers?

This conversion helps quantify extremely large distances using an extremely small unit, allowing precise scientific calculations that span vastly different length scales.

Is this conversion used in everyday measurements?

No, due to the huge difference in scale, converting AU to nm is primarily for scientific contexts like astronomy, astrophysics, and nanotechnology research.
