About these units
Yard (yd)
A yard equals 3 feet or 36 inches and serves as a mid-range imperial length unit. Historically, one definition of the yard was the distance from the tip of King Henry I's nose to his thumb when his arm was extended, though later attempts standardized the measure. Today, yards appear in sports (football, golf), textiles (fabric sales), and landscaping. In construction and engineering, the yard is sometimes used for larger distances where a foot would be too small a unit and a mile too large. Because it divides cleanly into both inches and feet, the yard plays a structural role in the imperial measurement system. It bridges the gap between human-scale and large-scale distances.
Megaparsec (Mpc)
A megaparsec is equal to one million parsecs, making it one of the principal units for describing intergalactic distances and the scale of the observable universe. Astronomers use Mpc to measure the distances between galaxies, galaxy groups, and galaxy clusters, as well as to express the scale of cosmic structures like the cosmic web. Megaparsecs are also central to cosmology because the Hubble constant — which describes the rate of cosmic expansion — is measured in units of kilometers per second per megaparsec. Thus, the Mpc sits at the heart of research on dark energy, large-scale structure formation, and the Big Bang. While hardly intuitive for everyday understanding, the megaparsec offers unmatched practicality for professional astronomy. It simplifies equations and visualization of the universe at the grandest scales.
