Units explained
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.
Combines the metric-style prefix kilo- with the parsec. Standardised in astronomy as the natural unit for distances within and between galaxies.
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.
Exact via the parsec; standardised by IAU 2015 along with parsec.
Yard
A yard is an Imperial and US customary unit of length equal to 3 feet or exactly 0.9144 meters. It is used for medium distances, particularly in athletics and fabric/textile measurement.
The yard's origin is contested but traditionally attributed to the length from the tip of King Henry I's nose to the end of his outstretched thumb. It was standardized in English law from the medieval period and definitively fixed at 0.9144 m exactly by the 1959 International Yard and Pound Agreement.
Yards are used in American football (10 yards for a first down), golf course distances, fabric and carpet sales in the US, and short-distance running events. The UK uses yards informally and on road signs for short distances.
Standardized in English law from the Middle Ages; fixed at 0.9144 m exactly by the 1959 International Yard and Pound Agreement.
Kiloparsec to Yard conversion formula
The relationship between kiloparsecs and yards:
To convert kiloparsecs to yards, multiply the value in kiloparsecs by 3.374538e+19. To reverse, multiply yards by 2.963369e-20.

Step-by-step: convert kiloparsecs to yards
- Write down the value in kiloparsecs (kpc).
- Multiply that value by the factor 3.374538e+19.
- The product is the equivalent value in yards (yd).
- To reverse, multiply the yard value by 2.963369e-20.
Worked examples
Example 1 — Convert 1 kpc to yd:
