Metric Conversion Practice Worksheet Answers

Converting between different units of measurement is a crucial skill in various fields, including science, engineering, and everyday life. The metric system, also known as the International System of Units (SI), is widely used around the world. In this worksheet, we will provide answers to common metric conversion problems.

Length Conversions

Length is a fundamental physical quantity that can be measured in various units, including meters (m), centimeters (cm), millimeters (mm), kilometers (km), and more. Here are some common length conversions:

• 1 meter (m) = 100 centimeters (cm) = 1000 millimeters (mm)
• 1 kilometer (km) = 1000 meters (m) = 1,000,000 millimeters (mm)
• 1 centimeter (cm) = 10 millimeters (mm)

Examples and Answers

1. Convert 5 meters to centimeters.

   📝 Note: Multiply 5 meters by 100 to get centimeters.

   Answer: 5 m × 100 = 500 cm

2. Convert 250 millimeters to meters.

   📝 Note: Divide 250 millimeters by 1000 to get meters.

   Answer: 250 mm ÷ 1000 = 0.25 m

3. Convert 3 kilometers to millimeters.

   📝 Note: Multiply 3 kilometers by 1,000,000 to get millimeters.

   Answer: 3 km × 1,000,000 = 3,000,000 mm

Mass Conversions

Mass is another important physical quantity that can be measured in various units, including grams (g), kilograms (kg), and milligrams (mg). Here are some common mass conversions:

• 1 kilogram (kg) = 1000 grams (g) = 1,000,000 milligrams (mg)
• 1 gram (g) = 1000 milligrams (mg)

Examples and Answers

1. Convert 2 kilograms to grams.

   📝 Note: Multiply 2 kilograms by 1000 to get grams.

   Answer: 2 kg × 1000 = 2000 g

2. Convert 500 milligrams to grams.

   📝 Note: Divide 500 milligrams by 1000 to get grams.

   Answer: 500 mg ÷ 1000 = 0.5 g

3. Convert 5 kilograms to milligrams.

   📝 Note: Multiply 5 kilograms by 1,000,000 to get milligrams.

   Answer: 5 kg × 1,000,000 = 5,000,000 mg

Volume Conversions

Volume is a measure of the amount of space occupied by a substance. Common units of volume include liters (L), milliliters (mL), and cubic meters (m³). Here are some common volume conversions:

• 1 liter (L) = 1000 milliliters (mL) = 0.001 cubic meters (m³)
• 1 milliliter (mL) = 0.001 liters (L)

Examples and Answers

1. Convert 2 liters to milliliters.

   📝 Note: Multiply 2 liters by 1000 to get milliliters.

   Answer: 2 L × 1000 = 2000 mL

2. Convert 500 milliliters to liters.

   📝 Note: Divide 500 milliliters by 1000 to get liters.

   Answer: 500 mL ÷ 1000 = 0.5 L

3. Convert 3 liters to cubic meters.

   📝 Note: Multiply 3 liters by 0.001 to get cubic meters.

   Answer: 3 L × 0.001 = 0.003 m³

Temperature Conversions

Temperature is a measure of the thermal energy of a substance. Common units of temperature include Celsius (°C), Fahrenheit (°F), and Kelvin (K). Here are some common temperature conversions:

• 1°C = 33.8°F = 274.15 K
• 1°F = -17.22°C = 255.37 K

Examples and Answers

1. Convert 25°C to Fahrenheit.

   📝 Note: Multiply 25°C by 1.8 and add 32 to get Fahrenheit.

   Answer: 25°C × 1.8 + 32 = 77°F

2. Convert 100°F to Celsius.

   📝 Note: Subtract 32 from 100°F and divide by 1.8 to get Celsius.

   Answer: (100°F - 32) ÷ 1.8 = 37.78°C

3. Convert 0°C to Kelvin.

   📝 Note: Add 273.15 to 0°C to get Kelvin.

   Answer: 0°C + 273.15 = 273.15 K

The answers to these common metric conversion problems will help you become more proficient in converting between different units of measurement.
