Kiloparsec

What is a kiloparsec?

A kiloparsec is a distance unit equal to 1,000 parsecs (about 3.09×10¹⁹ m). It is used to express galactic-scale distances.

Origin of the kiloparsec

Combines the metric-style prefix kilo- with the parsec. Standardised in astronomy as the natural unit for distances within and between galaxies.

Where it is used

Kiloparsecs are used to express galactic radii (the Milky Way is roughly 8 kpc from center to Sun), galactic-cluster scales, and distances within the Local Group.

When and where it was developed

Exact via the parsec; standardised by IAU 2015 along with parsec.

Imperial / US Customary

Mile

What is a mile?

A mile (statute mile) is an Imperial and US customary unit of length equal to 5,280 feet or exactly 1,609.344 meters. It is the standard unit for road distances in the United States and the United Kingdom.

Origin of the mile

The mile derives from the Roman mille passus ("thousand paces" — about 1,480 meters). The English statute mile was fixed at 5,280 feet by the Weights and Measures Act of 1593, and exactly defined as 1,609.344 m by the 1959 International Yard and Pound Agreement.

Where it is used

Miles are used in the US and UK for road signs, speed limits (mph), athletic events (one-mile run), and geographic distances. Aviation also uses statute miles for some visibility measurements.

When and where it was developed

Roman origin (mille passus); English statute mile fixed at 5,280 feet in 1593; standardized to 1,609.344 m exactly by the 1959 International Yard and Pound Agreement.

Kiloparsec to Mile conversion formula

The relationship between kiloparsecs and miles:

1 kpc = 1.917351e+16 mi
1 mi = 5.215529e-17 kpc

To convert kiloparsecs to miles, multiply the value in kiloparsecs by 1.917351e+16. To reverse, multiply miles by 5.215529e-17.

Step-by-step: convert kiloparsecs to miles

  1. Write down the value in kiloparsecs (kpc).
  2. Multiply that value by the factor 1.917351e+16.
  3. The product is the equivalent value in miles (mi).
  4. To reverse, multiply the mile value by 5.215529e-17.

Worked examples

Example 1 — Convert 1 kpc to mi:
1 × 1.917351e+16 = 1.917351e+16 mi

Example 2 — Convert 100 kpc to mi:
100 × 1.917351e+16 = 1.917351e+18 mi
