Compare and convert metric units of length

Key Notes :

Understanding Metric Units:

• The metric system uses units like millimeters (mm), centimeters (cm), meters (m), and kilometers (km) to measure length.
• Each unit is 10 times larger or smaller than the next, which makes converting between them easy.

Conversion Between Units:

• 1 meter (m) = 100 centimeters (cm)
• 1 centimeter (cm) = 10 millimeters (mm)
• 1 kilometer (km) = 1000 meters (m)

To convert:

• To go from a smaller unit to a larger unit, divide by 10, 100, or 1000.
• To go from a larger unit to a smaller unit, multiply by 10, 100, or 1000.

Comparing Metric Units:

• The larger the unit, the fewer numbers you need to represent the same length. For example, 100 cm is equal to 1 meter.
• Use the appropriate unit depending on the length. For small lengths, millimeters or centimeters are best. For larger distances, use meters or kilometers.

Examples of Conversion:

• 1500 millimeters (mm) = 150 centimeters (cm) = 1.5 meters (m).
• 2.5 kilometers (km) = 2500 meters (m).
