About these units
Mile (Roman) (mi (Roman))
The Roman mile was defined as 1,000 paces (mille passus), approximately 1,479 meters. It was used throughout the Roman Empire to standardize distances along roads, military routes, and territorial boundaries. Roman engineers laid out roads using milestones measured in miles, which facilitated logistics, military coordination, and trade. The mile also influenced subsequent measurement systems in medieval Europe, forming the basis for the English mile. Understanding the Roman mile is essential for archaeologists, historians, and engineers studying ancient infrastructure, providing insight into the efficiency and planning of the Roman transportation network.
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.
