asked in category: General Last Updated: 26th June, 2020# What is the largest unit of distance?

**gigaparsec**(Gpc) is one billion

**parsecs**— one of the largest units of length commonly used. One

**gigaparsec**is about 3.26 billion

**light-years**, or roughly 114 of the distance to the horizon of the observable universe (dictated by the cosmic background radiation).

Likewise, people ask, what are the units of measure for distance?

In the metric system of **measurement**, the most common **units** of **distance** are millimeters, centimeters, meters, and kilometers.

Also, what are the metric units in order from smallest to largest? The **millimeter** (mm) is the smallest metric measure of length and equals 1/1000 of a **meter**. The **centimeter** (**cm**) is the next largest unit of length and equals 1/100 of a **meter**. The **decimeter** (dm) is the next largest unit of length and equals 1/10 of a **meter**.

Likewise, people ask, what is the smallest unit of distance?

Millimeter is the **smallest unit of length** that is represented as 'mm'. It is directly related to other **units of length** like meter and kilometer. Hence we can convert the mm to m and km easily with the help of these **units**.
