How to Convert Between Km, m, cm, and mm?
FAQs on Metric Units of Length Worksheet for Class 4
1. What are the metric units of length for Class 4?
For Class 4 students, the main metric units of length covered in the maths syllabus are kilometer (km), meter (m), centimeter (cm), and millimeter (mm).
- Kilometer (km): Used for measuring very long distances, like the distance between two cities.
- Meter (m): A standard unit used for measuring lengths such as the height of a room or the length of a playground.
- Centimeter (cm): Used for measuring smaller objects, for example, the length of a pencil or a book.
- Millimeter (mm): Used for measuring very small lengths, like the thickness of a coin or a piece of paper.
2. How do you convert units of length like km, m, cm, and mm?
You can convert between metric units of length by remembering their basic relationships and using multiplication or division by 10, 100, or 1000.
- 1 kilometer (km) = 1000 meters (m)
- 1 meter (m) = 100 centimeters (cm)
- 1 centimeter (cm) = 10 millimeters (mm)
To convert from a larger unit to a smaller unit, you multiply. To convert a smaller unit to a larger one, you divide. This length conversion skill is a key part of the Grade 4 curriculum.
3. Does this worksheet on metric units of length include an answer key?
Yes, this Class 4 Maths worksheet on metric units comes with a complete answer key for all questions.
The included answers allow parents and students to quickly check their work after completing the unit conversion exercises. This is ideal for easy at-home correction and helps reinforce learning by identifying and correcting mistakes immediately.
4. Is this Grade 4 measurement worksheet available as a printable PDF?
Absolutely. This Grade 4 measurement worksheet is designed as a free, printable PDF for your convenience.
You can easily download the worksheet for offline practice, making it a perfect resource for homework, classroom revision, or extra practice on metric measurement. The PDF format ensures it prints clearly for easy use by students.

- For Practice: The printable PDF format allows for repeated practice to build confidence and fluency.
8. What is the basic relationship between the four metric units of length?
The relationship between the metric units of length is based on a decimal system (multiples of 10), which makes metric conversions straightforward.
The metric scale for length follows this order from largest to smallest:
- 1 Kilometer (km) = 1,000 Meters
- 1 Meter (m) = 100 Centimeters
- 1 Centimeter (cm) = 10 Millimeters
Understanding this metric table is a core part of the Class 4 Maths syllabus on measurement.
9. What is the best way to remember the metric conversion chart for length?
A great way to remember the metric conversion chart is by using a mnemonic device or visualising a 'metric ladder'.
Think of the units as steps on a ladder: Kilometer (km) is at the top, followed by Meter (m), Centimeter (cm), and Millimeter (mm) at the bottom.
- To go down the ladder (from a bigger unit to a smaller one), you multiply.
- To go up the ladder (from a smaller unit to a bigger one), you divide.
This worksheet provides exercises to master these step-by-step conversions.
10. What age group is this metric units worksheet best for?
This worksheet on metric units of length (km, m, cm, mm) is specifically designed for Grade 4 students, who are typically 9-10 years old.
The content, question types, and difficulty level are aligned with the standard Class 4 Maths curriculum. It can also be used by Grade 3 students for an advanced challenge or by Grade 5 students for revision of foundational measurement concepts.
