no the measure it in AU'S =ASTRONOMICAL UNITS
To measure the width of the solar system, astronomers use astronomical units (AU) as a common distance measurement. One astronomical unit is the average distance from Earth to the sun, approximately 93 million miles. This unit helps provide a scale for understanding distances within our solar system.
Astronomers estimate that UB313, also known as Eris, is about 1,445 miles (2,326 kilometers) in diameter. It is one of the largest known dwarf planets in our solar system.

Kilometers
The metric system is used to measure distance in Brazil. Distances are typically measured in kilometers (km) and meters (m).
Mainly astronomers. But cosmologists and astrophysicists will also be interested in outer space.
Kilometers per hour, meters per second, etc.
Through the International Decimal System (kilometers, liters, square meters).
Mexico primarily uses the metric system to measure length and distance. Common units include centimeters, meters, and kilometers. In some cases, inches and feet from the imperial system may also be used in informal settings.
A "light year" is probably the best known measure. That's how far light travels through space in a year. Professional astronomers also use a measure called a "parsec". Of course, for relatively small distances miles and kilometers are used. Another unit used within our solar system is the astronomical unit (AU), which is equal to the average distance between Earth and the sun (about 93 million miles or about 150 gigameters).
