What is Length?

Length is the measurement of how long or how far something is from one end to the other. It is one of the fundamental measurements in geometry and is typically measured in units such as inches, feet, yards, centimeters, meters, and kilometers. Understanding length is important for many real-world applications, such as measuring objects, designing buildings, and calculating distances.

Units of Length

There are several units of length commonly used in measurement. Some of the most common units include:

Inches (in)
Feet (ft)
Yards (yd)
Miles (mi)
Centimeters (cm)
Meters (m)
Kilometers (km)

Converting Units of Length

Converting between units of length is an important skill to have. Here are some common conversion factors:

1 foot = 12 inches
1 yard = 3 feet
1 mile = 5280 feet
1 meter = 100 centimeters
1 kilometer = 1000 meters

How to Measure Length

There are different tools used to measure length, such as rulers, yardsticks, tape measures, and meter sticks. When measuring length, it's important to align the starting point of the object with the zero mark of the measuring tool and read the measurement at the end point of the object.
