Free Grade 4 Converting Metric Units Practice

Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit.

Topic Overview

Definitive Answer: Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit.

Imagine you have a long jump rope. You might measure it in **meters** or **centimeters**! Sometimes, you need to change a measurement from one unit to another, like changing 2 **meters** into **centimeters**. This is called **converting** units. When you convert from a **bigger unit** (like meters) to a **smaller unit** (like centimeters or millimeters), you **multiply**. We'll focus on multiplying by 10 or 100 for length conversions today!

Step-by-Step Examples

Example 1: A ribbon is 2 meters long. How many centimeters long is the ribbon?
  1. **Step 1:** Identify the units. We are changing meters (a bigger unit) to centimeters (a smaller unit).
  2. **Step 2:** Remember the relationship: 1 meter = 100 centimeters.
  3. **Step 3:** Since we're going from a bigger unit to a smaller unit, we **multiply**. So, 2 meters * 100 = 200 centimeters.
✓ Answer: 200 centimeters
Example 2: A pencil is 15 centimeters long. How many millimeters long is the pencil?
  1. **Step 1:** Identify the units. We are changing centimeters (a bigger unit) to millimeters (a smaller unit).
  2. **Step 2:** Remember the relationship: 1 centimeter = 10 millimeters.
  3. **Step 3:** Since we're going from a bigger unit to a smaller unit, we **multiply**. So, 15 centimeters * 10 = 150 millimeters.
✓ Answer: 150 millimeters
