Units explained
Megaparsec
A megaparsec is a distance unit equal to one million parsecs (about 3.09×10²² m). It is the standard unit for cosmological-scale distances.
Combines the metric-style prefix mega- with the parsec. Standardised in astronomy for inter-galactic distances and cosmological calculations.
Megaparsecs are used in cosmology to express distances to other galaxies (Andromeda is ~0.78 Mpc), galaxy-cluster separations, and the Hubble constant (typically quoted as ~70 km/s per Mpc).
Exact via the parsec; the megaparsec is the standard scale unit in modern cosmology.
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.
Megaparsec to Yard conversion formula
The relationship between megaparsecs and yards:
To convert megaparsecs to yards, multiply the value in megaparsecs by 3.374538e+22. To reverse, multiply yards by 2.963369e-23.

Step-by-step: convert megaparsecs to yards
- Write down the value in megaparsecs (Mpc).
- Multiply that value by the factor 3.374538e+22.
- The product is the equivalent value in yards (yd).
- To reverse, multiply the yard value by 2.963369e-23.
Worked examples
Example 1 — Convert 1 Mpc to yd:
