1 parsec (pc) = 3.08568E+13 kilometer (km). Parsec (pc) is a unit of Length used in Metric system. Kilometer (km) is a unit of Length used in Metric system.

Parsec: A Unit of Length

A parsec is a unit of length that is often used in astronomy to measure the large distances to astronomical objects outside the Solar System. It is approximately equal to 3.26 light-years or 206,265 astronomical units (au), which are the average distances from the Earth to the Sun. One parsec is about 30.9 trillion kilometres or 19.2 trillion miles.

How to convert parsec

To convert parsecs to other units of length, we can use the following conversion factors:

• 1 pc = 3.0857 × 10^¹⁶ m
• 1 pc = 1.9174 × 10^¹³ mi
• 1 pc = 2.06265 × 10^⁵ au
• 1 pc = 3.26156 ly

To convert other units of length to parsecs, we can use the inverse of these conversion factors:

• 1 m = 3.24078 × 10^^-17 pc
• 1 mi = 5.21553 × 10^^-14 pc
• 1 au = 4.84814 × 10^^-6 pc
• 1 ly = 0.306601 pc

• How many parsecs are in one light-year?

To convert one light-year to parsecs, we divide by the conversion factor:

1 ly / (3.26156 ly/pc) = 0.306601 pc

Kilometer - Unit of Distance / Length

Unit Symbol / Abbreviation: km

Where the unit used in the World:

The kilometer is used as a unit used to measure distances or lengths.
It's a standard measure for travelled distances, geographical distances and maps in most countries excluding the USA and the United Kingdom where mile is still used for this purpose.
between geographical locations on land, and in most countries is the official unit for this purpose. Primary exceptions are the United Kingdom, Liberia, Myanmar and the United States of America, where the mile remains as standard as a part of imperial system.

Definition of the Unit:

The kilometer (kilometre in UK spelling) is a unit of length/distance in the metric system (SI Unit system) equivalent to one thousand meters.

1 km is equivalent to 0.62137 miles.

• 1 km = 1000000 millimeters (mm)
• 1 km = 100 000 centimeters (cm)
• 1 km = 10000 decimeters (dm)
• 1 km = 1000 meters (m)
• 1 km = 3280.84 feet (ft)
• 1 megameter = 1000 km
• 1 gigameter = 1000000 km
• 1 mile = 1.609 km
• 1 yard = 0.000914 km
• 1 foot = 0.000305 km
• 1 inch = 0.0000254 km
• Units of length in the metric SI system are based on multiples or fractions of a meter.
• There are measurements of length/distance in the metric SI system greater than a kilometer that can be expressed in terms of kilometres.

1 km is equivalent to 0.621371 mi.

The kilometer is unit of length in the metric SI system and is equivalent to one thousand metres.
