Convert Metric Units of Length

Welcome to a learning text on converting metric units of length! This topic is really important for understanding how different length units like millimetres, centimetres, metres and kilometres relate to each other in the metric system. If you need some background learning on metric measurements, then check out Millimetres, Centimetres, Metres and Kilometres first! Mastering this topic will assist you in everyday measurements and maths problems involving length. Let's dive in and make these conversions easy to grasp.

Understanding Converting Metric Units of Length

Converting metric units of length means changing a measurement from one unit, like centimetres, to another, like metres, within the metric system.

To convert between these units, we use multiplication or division based on their relationship to each other.

When converting from a smaller unit to a larger unit, you use division. When converting from a larger unit to a smaller unit, you use multiplication. Here's a detailed explanation:

  • Converting between millimetres and centimetres: Since there are 10 millimetres in a centimetre, to convert millimetres to centimetres, you divide the number of millimetres by 10. To convert centimetres to millimetres, multiply the number of centimetres by 10.

  • Converting between centimetres and metres: There are 100 centimetres in a metre. To convert centimetres to metres, divide the number of centimetres by 100. To convert metres to centimetres, multiply the number of metres by 100.

  • Converting between metres and kilometres: One kilometre equals 1,000 metres. To find out how many kilometres are in a certain number of metres, divide the number of metres by 1,000. To find out how many metres are in a certain number of kilometres, multiply the number of kilometres by 1,000.

Here's a simple table to help you remember these key conversions:

Unit Equals
1 centimetre 10 millimetres
1 metre 100 centimetres
1 kilometre 1,000 metres

Let’s check your understanding before we practise converting metric units of length.

When converting from a larger unit to a smaller unit, what mathematical operation do you use?

Convert Metric Units of Length – Step-by-Step Examples

Now we can walk through how to convert metric units of lengths with two examples. Make sure to follow along carefully to understand the step-by-step solution.

First, let’s convert 500 millimetres to centimetres.

Understand the Relationship: Remember that 1 centimetre is equal to 10 millimetres. This means for every 10 millimetres, we have 1 centimetre.

Set Up the Operation: Since you have 500 millimetres, and you need to find out how many centimetres that is, you'll divide since you are converting a smaller unit to a larger unit.

Calculate: Perform the division: 500 ÷ 10 = 50.

Conclusion: So, 500 millimetres are equal to 50 centimetres.

Now let’s convert 3 metres to centimetres.

Understand the Relationship: Remember that 1 metre equals 100 centimetres.

Set Up the Operation: You have 3 metres, and you want to know how many centimetres that is. Since each metre is 100 centimetres, you will multiply, since you are converting a larger unit to a smaller unit.

Calculate: Perform the multiplication: 3 x 100 = 300.

Conclusion: Therefore, 3 metres equals 300 centimetres.

Following these steps and thought processes as you convert metric units of length will help you. Make a note of the steps if you need to!
