Answer Key: Metric Conversion Worksheet with Answers for Chemistry

Metric conversions are a crucial aspect of chemistry, as they allow scientists to express measurements in a standardized and consistent manner. In this worksheet, we will practice converting between different units of measurement, focusing on the metric system. By the end of this exercise, you will be able to confidently convert between various units, ensuring accuracy in your calculations.

Metric Conversion Basics

Before we begin, let’s review the basics of metric conversion. The metric system is based on the International System of Units (SI), which includes seven base units:

• meter (m) for length
• gram (g) for mass
• liter (L) for volume
• second (s) for time
• kelvin (K) for temperature
• mole (mol) for amount of substance
• candela (cd) for luminous intensity

Conversion Factors

To convert between different units, we use conversion factors. A conversion factor is a ratio of two units that is equal to 1. For example:

1 meter (m) = 100 centimeters (cm) 1 liter (L) = 1000 milliliters (mL)

We can use these conversion factors to convert between units. For instance:

• To convert 25 cm to meters, we multiply 25 cm by the conversion factor (1 m / 100 cm): 25 cm × (1 m / 100 cm) = 0.25 m
• To convert 250 mL to liters, we multiply 250 mL by the conversion factor (1 L / 1000 mL): 250 mL × (1 L / 1000 mL) = 0.25 L

Worksheet: Metric Conversions

Now, let’s practice converting between different units with the following worksheet:

1. Convert 50 grams to milligrams.
2. Convert 250 milliliters to liters.
3. Convert 10 kilometers to meters.
4. Convert 500 seconds to minutes.
5. Convert 25 degrees Celsius to kelvin.

📝 Note: Use the conversion factors provided above to solve these problems.

Answers:

1. 50 grams = 50,000 milligrams (g × 1000 mg/g)
2. 250 milliliters = 0.25 liters (mL × 1 L / 1000 mL)
3. 10 kilometers = 10,000 meters (km × 1000 m/km)
4. 500 seconds = 8.33 minutes (s × 1 min / 60 s)
5. 25 degrees Celsius = 298.15 kelvin (°C + 273.15)

Additional Conversion Factors

Here are some additional conversion factors that you may find useful:

• 1 meter = 3.28 feet (ft)
• 1 liter = 1.06 quarts (qt)
• 1 gram = 0.0353 ounces (oz)
• 1 degree Celsius = 1.8 degrees Fahrenheit (°F)

Practice Problems

Now that you have practiced converting between different units, try these additional problems:

1. Convert 200 feet to meters.
2. Convert 500 ounces to grams.
3. Convert 10 quarts to liters.
4. Convert 250 degrees Fahrenheit to Celsius.
5. Convert 500 minutes to hours.

📝 Note: Use the conversion factors provided above to solve these problems.

Answers:

1. 200 feet = 60.96 meters (ft × 0.3048 m/ft)
2. 500 ounces = 14,174 grams (oz × 28.35 g/oz)
3. 10 quarts = 9.46 liters (qt × 0.946 L/qt)
4. 250 degrees Fahrenheit = 121.11 degrees Celsius (°F - 32 × ⁵⁄₉)
5. 500 minutes = 8.33 hours (min × 1 hr / 60 min)

In Conclusion

In this worksheet, we have practiced converting between different units of measurement, focusing on the metric system. By mastering these conversions, you will be able to accurately express measurements in a standardized and consistent manner, ensuring precision in your calculations. Remember to use conversion factors to simplify your conversions, and don’t hesitate to practice with additional problems to reinforce your understanding.
