How to Convert Between Kilometers, Meters, Centimeters, and Millimeters
FAQs on Metric Units of Length Practice Worksheet for Class 4
1. What are the metric units of length for Class 4?
The main metric units of length for Class 4 are used to measure how long or far something is. These units are organized from largest to smallest to measure everything from the distance between cities to the width of a pencil tip.
- Kilometer (km): Used for measuring very long distances, like the length of a road.
- Meter (m): Used for measuring medium lengths, like the height of a door or the length of a room.
- Centimeter (cm): Used for measuring smaller objects, like a book or a pencil.
- Millimeter (mm): Used for measuring very small lengths, like the thickness of a coin.
2. How do you convert from kilometers to meters?
To convert from kilometers (km) to meters (m), you multiply the number of kilometers by 1,000. This is because there are 1,000 meters in a single kilometer.
- The Rule: 1 km = 1000 m.
- Example: To convert 5 kilometers to meters, you calculate 5 x 1000, which equals 5000 meters.
3. How do you use decimals in length conversions?
Decimals are used in length conversions to represent a part of a larger unit. For example, when converting a smaller unit like centimeters to a larger unit like meters, the result is often a decimal number.
- Converting cm to m: Since 1 m = 100 cm, you divide the number of centimeters by 100. For instance, 75 cm is equal to 0.75 m.
- Converting m to km: Since 1 km = 1000 m, you divide the number of meters by 1000. For instance, 500 m is equal to 0.5 km.
4. What is the relation between meter (m) and centimeter (cm)?
The relationship between meters (m) and centimeters (cm) is a fundamental part of the metric system. One meter is equal to one hundred centimeters, making the centimeter a smaller unit of length.
- The Conversion Rule: 1 meter = 100 centimeters.
- Practical Use: This conversion is used for everyday measurements, like measuring cloth or the height of a person. A person who is 1.5 meters tall is 150 centimeters tall.
