This comprehensive guide provides answer keys and explanations for common metric conversion worksheets, covering length, mass, volume, and temperature. We'll tackle the most frequently encountered conversions, ensuring you understand the process and can confidently solve similar problems. Whether you're a student, teacher, or simply brushing up on your metric system knowledge, this guide will be an invaluable resource.
While I can't provide specific answers to a specific worksheet you haven't provided, I can walk you through the methods and provide examples to help you solve any metric conversion problem. Remember, the key to mastering metric conversions is understanding the base units and the prefixes used to denote multiples and submultiples of those units.
Understanding the Metric System
The metric system, also known as the International System of Units (SI), is based on powers of 10. This makes conversions remarkably straightforward. The fundamental units are:
- Length: Meter (m)
- Mass: Gram (g)
- Volume: Liter (L)
- Temperature: Celsius (°C)
The prefixes used to modify these base units are:
| Prefix | Symbol | Multiplier |
|---|---|---|
| Kilo | k | 1000 (10³) |
| Hecto | h | 100 (10²) |
| Deka | da | 10 (10¹) |
| Deci | d | 0.1 (10⁻¹) |
| Centi | c | 0.01 (10⁻²) |
| Milli | m | 0.001 (10⁻³) |
Common Metric Conversions & Examples
Let's go through some common conversion scenarios:
1. Length Conversions
Example 1: Convert 2.5 kilometers (km) to meters (m).
Since 1 km = 1000 m, we multiply: 2.5 km * 1000 m/km = 2500 m
Example 2: Convert 150 centimeters (cm) to meters (m).
Since 1 m = 100 cm, we divide: 150 cm / 100 cm/m = 1.5 m
2. Mass Conversions
Example 1: Convert 5000 grams (g) to kilograms (kg).
Since 1 kg = 1000 g, we divide: 5000 g / 1000 g/kg = 5 kg
Example 2: Convert 25 milligrams (mg) to grams (g).
Since 1 g = 1000 mg, we divide: 25 mg / 1000 mg/g = 0.025 g
3. Volume Conversions
Example 1: Convert 3 liters (L) to milliliters (mL).
Since 1 L = 1000 mL, we multiply: 3 L * 1000 mL/L = 3000 mL
Example 2: Convert 750 milliliters (mL) to liters (L).
Since 1 L = 1000 mL, we divide: 750 mL / 1000 mL/L = 0.75 L
4. Temperature Conversions (Celsius to Fahrenheit and vice versa)
These conversions are slightly more complex:
- Celsius to Fahrenheit: °F = (°C * 9/5) + 32
- Fahrenheit to Celsius: °C = (°F - 32) * 5/9
Example 1: Convert 20°C to Fahrenheit.
°F = (20 * 9/5) + 32 = 68°F
Example 2: Convert 77°F to Celsius.
°C = (77 - 32) * 5/9 = 25°C
Troubleshooting Your Worksheet
To get help with your specific worksheet, please provide the following:
