Inch

An inch is a unit of length used primarily in the imperial and U.S. customary systems. It is commonly used in countries like the United States, Canada, and the UK for measuring shorter lengths. One inch equals 2.54 centimeters. There are 12 inches in a foot. Inches are often used to measure things like screen sizes, paper dimensions, or body measurements. For example, a standard smartphone screen might be about 6 inches. The symbol for inch is "in" or a double quote mark (″). Rulers, measuring tapes, and toolkits often include inches for easy reference. Although the metric system is more widely used globally, inches remain common in certain industries and countries for specific applications.

Light Year

A light year is a unit of distance used in astronomy to measure how far light travels in one year. Light moves extremely fast—about 299,792 kilometers per second—so in one year, it travels roughly 9.46 trillion kilometers (or about 5.88 trillion miles). Light years help scientists express the huge distances between stars and galaxies. For example, the nearest star to Earth, Proxima Centauri, is about 4.24 light years away. The term “light year” can be confusing because it sounds like a measure of time, but it actually measures distance.
