straightforward once the basic prefixes are understood.
Common Metric Prefixes
kilo- (k): 1,000 units
hecto- (h): 100 units
deka- (da): 10 units
base unit: 1 unit (meter, liter, gram)
deci- (d): 0.1 units
centi- (c): 0.01 units
milli- (m): 0.001 units
micro- (μ): 0.000001 units
Why Practice Metric Conversion Problems?
Practicing metric conversion problems enhances your ability to:
Convert measurements accurately across different units

Problem 1: Converting Lengths
Convert 5 kilometers to meters.
Solution:
Recall that 1 kilometer = 1,000 meters.
Therefore, 5 km = 5 × 1,000 m = 5,000 meters.
Problem 2: Volume Conversion
Convert 3.5 liters to milliliters.
Solution:
Recall that 1 liter = 1,000 milliliters.
So, 3.5 L = 3.5 × 1,000 mL = 3,500 milliliters.
Problem 3: Mass Conversion
Convert 250 grams to kilograms.
Solution:
Recall that 1 kilogram = 1,000 grams.
Therefore, 250 g = 250 ÷ 1,000 kg = 0.25 kilograms.
Problem 4: Combining Units
Convert 0.75 meters to centimeters.
Solution:
Recall that 1 meter = 100 centimeters.
Thus, 0.75 m = 0.75 × 100 cm = 75 centimeters.
Problem 5: Large Measurements
Convert 2,500 millimeters to meters.
Solution:
Recall that 1 meter = 1,000 millimeters.
So, 2,500 mm = 2,500 ÷ 1,000 m = 2.5 meters.
Problem 6: Small Measurements
Convert 0.003 grams to milligrams.
3
Solution:
Recall that 1 gram = 1,000 milligrams.
Thus, 0.003 g = 0.003 × 1,000 mg = 3 milligrams.

Problem 7: Temperature Conversion
Convert 25°C to Fahrenheit.
Solution:
Use the formula: °F = (°C × 9/5) + 32.
Calculate: (25 × 9/5) + 32 = (25 × 1.8) + 32 = 45 + 32 = 77°F.
Problem 8: Combining Length and Volume
Convert 150 centimeters to meters and then to liters, assuming a 1:1 ratio for
volume (hypothetical).
Solution:
Convert centimeters to meters: 150 cm ÷ 100 = 1.5 meters.
For the purpose of this hypothetical problem, 1.5 meters is equivalent to 1.5 liters in
volume measurement.
Note: In real scenarios, length and volume are different units, but this illustrates unit
conversion within the metric system.
Problem 9: Converting Time-Related Measurements
Convert 3,600 seconds to hours.
Solution:
Recall that 1 hour = 3,600 seconds.
Therefore, 3,600 seconds = 1 hour.
Problem 10: Practice with Multiple Conversions
Convert 7.2 kilometers to centimeters.
Solution:
First, convert kilometers to meters: 7.2 km × 1,000 = 7,200 meters.
Then, convert meters to centimeters: 7,200 m × 100 = 720,000 centimeters.

Understanding the Metric System
Before diving into practice problems, it’s important to understand the fundamentals of the
metric system. The metric system is a decimal-based system of measurement used
worldwide for scientific, medical, and everyday measurements. Its simplicity and
scalability—based on powers of ten—make conversions straightforward once you
understand the units involved. Common Metric Units: - Length: kilometer (km), meter (m),
centimeter (cm), millimeter (mm) - Mass: kilogram (kg), gram (g), milligram (mg) -
Volume: liter (L), milliliter (mL) Conversion Factors: - 1 km = 1000 m - 1 m = 100 cm - 1
cm = 10 mm - 1 kg = 1000 g - 1 g = 1000 mg - 1 L = 1000 mL The key to mastering
metric conversions lies in understanding these relationships and applying the decimal
shift accordingly. ---
