What is Length?

Length is the measurement of how long or short an object is. It is a fundamental concept in mathematics and is used to quantify the distance between two points.

Units of Length

There are various units used to measure length, including:

• Millimeter (mm)
• Centimeter (cm)
• Meter (m)
• Kilometer (km)
• Inch (in)
• Foot (ft)
• Yard (yd)
• Mile (mi)

Converting Units of Length

It is important to be able to convert between different units of length. Here are some conversion factors to remember:

• 1 meter (m) = 100 centimeters (cm)
• 1 meter (m) = 1000 millimeters (mm)
• 1 kilometer (km) = 1000 meters (m)
• 1 inch (in) = 2.54 centimeters (cm)
• 1 foot (ft) = 12 inches (in)
• 1 yard (yd) = 3 feet (ft)
• 1 mile (mi) = 1760 yards (yd)

Measuring Length

Length can be measured using various tools such as rulers, meter sticks, measuring tapes, and trundle wheels. When measuring, it is important to ensure that the starting point and ending point are accurately identified, and the measurement is taken in a straight line.

Practice Problems

1. Convert 5 meters to centimeters.
2. What is the equivalent of 2.5 kilometers in meters?
3. If a notebook is 8 inches long, how many centimeters is that?

Answers

1. 5 meters = 500 centimeters
2. 2.5 kilometers = 2500 meters
3. 8 inches = 20.32 centimeters
