# Lengths and Angles

Convert between different angle and length units and
perform longitude wrapping; convert units of distances along the surface
of the Earth

On a perfect sphere, the distance between points on the surface of the sphere can be represented by angles. For spherical models of the Earth, Moon, and other planetary bodies, Mapping Toolbox™ allows spherical distance conversion between common units of angles and length.

## Functions

## Topics

### Angles

**Angle Representations and Angular Units**

Use angles with Mapping Toolbox functions, convert between angle representations, and format angles as text.

### Lengths

**Length and Distance Units**

Linear measurements of arc lengths and distances on spheroids use the same units as on the plane, such as feet, meters, miles, and kilometers.

### Spherical Distance

**Distances on the Sphere**

You can represent distances on the sphere using angles or linear arc lengths.**Relationship Between Points on Sphere**

There are many ways to define the 2-D spatial relationship between two points on a perfect sphere, including azimuth, heading, spherical distance, linear distance, and range.
