## What is Area

Area measurements indicate the total size of a 2 dimensional shape. Put another way, area is the amount of space within the boundaries of 2 dimensional shapes, such as a rectangle or square.

When finding area, it is crucial to use the same unit of measure for all measurements. Area measurements are commonly used for construction material estimates and to identify property sizes.

## How to Convert Units of Area

There are two steps to convert a unit of area to a different unit.

First, you'll need to find the conversion ratio, or rate of one unit to another. You can find this on the conversion chart below.

Once you have the conversion ratio, multiply the value you want to convert by the conversion ratio.

## How to Calculate Area

Before you can convert though, you need to learn how to measure and calculate area.

You can calculate the area by multiplying the length by the width. This is the most commonly used formula to find area for a square or rectangular shape.

area = length × width
