1 Metric Capacity Conversion
Grade 4 Worksheet Exercise 1
Convert 3.5 liters to milliliters. Then convert 2,500 milliliters to liters. Express your answers in decimal form.
Definition:

Metric conversion: Converting between metric capacity units using powers of 10.

Grade 4 Method:
  1. Use the conversion factor: 1 liter = 1,000 milliliters
  2. To convert liters to milliliters: multiply by 1,000
  3. To convert milliliters to liters: divide by 1,000
  4. Express answers in decimal form
Problem 1
3.5 L → mL
Conversion
× 1,000
Result
3,500 mL
Step 1: Convert 3.5 liters to milliliters

3.5 L × 1,000 mL/L = 3,500 mL

Step 2: Convert 2,500 milliliters to liters

2,500 mL ÷ 1,000 mL/L = 2.5 L

Step 3: Verify the conversions

3,500 mL ÷ 1,000 = 3.5 L ✓

Step 4: Express in decimal form

3,500 mL = 3.5 L, 2.5 L = 2,500 mL

Final answer:

3.5 liters = 3,500 milliliters, 2,500 milliliters = 2.5 liters

Grade 4 Rules:

• Metric conversion: 1 liter = 1,000 milliliters

• Multiplication: To convert to smaller units, multiply by 1,000

• Division: To convert to larger units, divide by 1,000

2 Mixed System Conversion
Grade 4 Worksheet Exercise 2
A recipe calls for 1.5 liters of water. How many cups is this? (Hint: 1 cup ≈ 240 milliliters)
Definition:

Mixed system conversion: Converting between different measurement systems (metric to customary).

Start
1.5 L
To mL
× 1,000
To cups
÷ 240
Result
? cups
Step 1: Convert liters to milliliters

1.5 L × 1,000 mL/L = 1,500 mL

Step 2: Convert milliliters to cups

1,500 mL ÷ 240 mL/cup ≈ 6.25 cups

Step 3: Round to appropriate precision

≈ 6.25 cups ≈ 6 1/4 cups

Step 4: Verify the calculation

6.25 cups × 240 mL/cup = 1,500 mL = 1.5 L ✓

Final answer:

1.5 liters is approximately 6.25 cups (or 6 1/4 cups).

Grade 4 Rules:

• Mixed conversion: Use conversion factors between systems

• Approximation: 1 cup ≈ 240 milliliters

• Verification: Check your final answer

4 Decimal Capacity
Grade 4 Worksheet Exercise 4
A container holds 2.75 liters of juice. If each serving is 150 milliliters, how many full servings can be poured? What is the remainder?
Definition:

Decimal capacity: Working with fractional amounts using decimal notation.

Total
2.75 L
Per serving
150 mL
Calculate
Divide
Step 1: Convert liters to milliliters

2.75 L = 2.75 × 1,000 mL = 2,750 mL

Step 2: Divide total by serving size

2,750 mL ÷ 150 mL/serving = 18.33... servings

Step 3: Determine full servings

Full servings = 18 (round down to nearest whole number)

Step 4: Calculate remainder

Remainder = 2,750 - (18 × 150) = 2,750 - 2,700 = 50 mL

Final answer:

18 full servings can be poured with 50 milliliters remaining.

Grade 4 Rules:

• Decimal conversion: Convert to consistent units first

• Division: Use long division for accuracy

• Remainder: Calculate what's left over

5 Complex Real-world Problem
Grade 4 Worksheet Exercise 5
A factory produces 450 bottles per minute. Each bottle holds 330 milliliters. How many liters of liquid does the factory produce per hour? Express your answer in scientific notation.
Definition:

Complex problem: Multi-step problem involving rates and conversions.

Rate
450/min
Per bottle
330 mL
Time
1 hour
Step 1: Calculate bottles per hour

450 bottles/minute × 60 minutes/hour = 27,000 bottles/hour

Step 2: Calculate total milliliters

27,000 bottles × 330 mL/bottle = 8,910,000 mL

Step 3: Convert to liters

8,910,000 mL ÷ 1,000 mL/L = 8,910 L

Step 4: Express in scientific notation

8,910 L = 8.91 × 10³ L

Final answer:

The factory produces 8.91 × 10³ liters per hour.

Grade 4 Rules:
