Inch
An inch (in) is a standard unit of length in the imperial system, widely used in the United States, Canada, and the United Kingdom. It is defined as 1/12 of a foot or exactly 25.4 millimeters in the metric system. Inches are commonly used to measure screen sizes, clothing, paper dimensions, and everyday household items.
Because many industries still rely on imperial measurements, converting inches to centimeters, feet, or other units is often necessary. A reliable converter helps ensure accuracy, especially when handling technical specifications.
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.
