Parsec
A parsec (pc) is a unit of length used in astronomy to measure huge distances between celestial objects. It equals about 3.26 lightyears, or 31 trillion kilometers (19 trillion miles). The name comes from “parallax arcsecond,” referring to the way astronomers calculate distances by measuring the slight shift of stars in the sky.
The parsec helps express distances that are far too vast for lightyears or kilometers. Converting parsecs to other astronomical units makes the scale of the universe easier to understand for scientists and space explorers.
Yard
A yard (yd) is an imperial unit of length equal to 3 feet or 0.9144 meters. It is commonly used in the United States and the United Kingdom for measuring fabric, sports fields, garden dimensions, and other medium-sized distances. Because it connects feet and miles, the yard plays a key role in everyday imperial measurements.
Whether comparing lengths for home projects, shopping, or athletics, converting yards into inches, feet, or meters is often useful. A conversion tool makes switching between systems quick and accurate.
