What is an astronomical unit (AU)?

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

What does a micron measure?

A micron, or micrometer, is a unit of length equal to one millionth of a metre, used to quantify microscopic dimensions like particles and biological cells.

Why convert from astronomical units to microns?

Converting from AU to microns helps express very large cosmic distances in microscopic terms for detailed scientific analysis and computational modeling.
