Parsec

A parsec (pc) is a unit of distance used in astronomy, equal to about 3.26 light-years or roughly 31 trillion kilometers. The name “parsec” comes from “parallax of one arcsecond,” referring to the method astronomers use to measure distances to nearby stars based on their apparent shift when viewed from different positions in Earth’s orbit. Parsecs are commonly used to measure distances to stars and galaxies. For example, the nearest star system, Alpha Centauri, is about 1.3 parsecs away. The symbol for parsec is "pc". It’s a convenient unit for expressing large astronomical distances beyond the reach of light-years.

Decimeter

A decimeter (dm) is a unit of length in the metric system. It is equal to one-tenth of a meter, or 10 centimeters (1 dm = 0.1 m = 10 cm). While not as commonly used as centimeters or meters in everyday life, decimeters are still important in scientific and technical measurements. For example, a small book or a tablet might be about 2 to 3 decimeters long. The symbol for decimeter is "dm". Although it sits between the centimeter and meter in size, people often skip using decimeters and go directly from centimeters to meters. Still, it's a helpful unit when you need a mid-sized measurement.
