Astronomical Unit
An astronomical unit (AU) is a unit of distance used in astronomy to describe the average distance between the Earth and the Sun. It equals about 149.6 million kilometers (or about 93 million miles). The AU is useful for measuring distances within our solar system, such as the distance from Earth to other planets. For example, Mars is about 1.5 AU from the Sun. Using the AU makes it easier to understand and compare distances between planets without dealing with very large numbers. The symbol for astronomical unit is "AU".
Fingerbreadth
A fingerbreadth is a traditional unit of length based on the width of a human finger, often used in historical and informal measurements. It typically measures about ¾ inch (approximately 19 millimeters), though it can vary depending on the person and context.
Fingerbreadths were commonly used in tailoring, medicine, and everyday life to estimate small lengths before standardized units became widespread.
