Convert Kilometer to Parsec

Type the number of kilometers that you wish to convert to parsecs.

1 km (kilometers) = 3.2404406999e-14 pc (parsecs)

How to Convert Kilometers to Parsecs

The kilometer and parsec are both units of length. By definition, 1 parsec equals exactly 3.086e13 kilometers. This means to convert kilometers to parsecs, you divide by 3.086e13.

Formula

parsecs = kilometers ÷ 3.086e13

Step-by-Step Example

Convert 5 km to parsecs:

1
Convert 5 km to parsecs

We need to convert kilometers to parsecs

2
Apply the formula

Since 1 pc = 3.086e13 km, divide by 3.086e13

5 ÷ 3.086e13 = 1.62022035e-13

Answer

5 km = 1.62022035e-13 pc

About These Units

Kilometer (km)

A kilometer (km) is a metric unit of length equal to 1,000 meters or approximately 0.621 miles. Kilometers are the standard unit for measuring road distances, running races, and geographic distances in most countries worldwide. Common conversions: 1 km = 0.621 miles, 1 mile = 1.609 km.

Parsec (pc)

A parsec (pc) is an astronomical unit equal to approximately 3.26 light years or 3.086×10¹⁶ meters. Parsecs measure stellar and galactic distances using parallax. The Milky Way galaxy is about 30,000 parsecs in diameter. Kiloparsecs (kpc) and megaparsecs (Mpc) measure larger cosmic distances.
