1. Conversion of Units of
Measurement
Mathematics 7 – Quarter 2

2. Learning Objectives
• At the end of the lesson, students should be
able to:
• 1. Explain the importance of converting units
of measurement.
• 2. Convert units of length, mass, and capacity
within the metric system.
• 3. Apply unit conversion in solving real-life
word problems.

3. Review / Balik-Aral
• • How many centimeters are there in 2
meters?
• • 1 kilometer = ? meters
• • Quick recall: metric units (mm, cm, m, km, g,
kg, L, mL)

4. Motivation
• Imagine: You have a ruler in centimeters but
the length is given in meters.
• • How can you measure it correctly?
• Answer: We convert units of measurement.

5. Lesson Proper – Discussion
• Metric System:
• • Based on powers of 10.
• • Common units:
• – Length: mm, cm, m, km
• – Mass: g, kg
• – Capacity: mL, L
• Conversion rule:
• • Move decimal RIGHT → smaller unit.

6. Examples
• 1. 3 m = 300 cm
• 2. 1500 g = 1.5 kg
• 3. 2.5 L = 2500 mL

7. Guided Practice
• Convert the following:
• 1. 4 km = ? m
• 2. 250 cm = ? m
• 3. 3.5 kg = ? g

8. Independent Activity
• Solve on your own:
• 1. 1.2 m = ? cm
• 2. 6000 m = ? km
• 3. 7500 mL = ? L

9. Application
• A water container holds 5 liters of water.
• • How many milliliters of water is this?
• Solution: 5 × 1000 = 5000 mL

10. Generalization
• • Conversion of units helps us compare and
understand measurements.
• • The metric system uses powers of 10 for
easy conversion.

11. Evaluation / Short Quiz
• Convert the following:
• 1. 7 km = ? m
• 2. 0.45 m = ? cm
• 3. 2000 g = ? kg
• 4. 3.75 L = ? mL
• 5. 90 cm = ? m

12. Assignment
• Measure 5 items at home.
• • Write their measurement in one unit.
• • Convert each measurement into two other
units.
