The Correct Answer and Explanation is:
1. How many centimeters are in 4.69 meters?
To convert meters to centimeters, use the conversion factor:
1 meter = 100 centimeters4.69 m×100=469 cm4.69 \, \text{m} \times 100 = 469 \, \text{cm}4.69m×100=469cm
✅ Answer: 469 cm
2. How many millimeters are in 6.05 meters?
1 meter = 1000 millimeters6.05 m×1000=6050 mm6.05 \, \text{m} \times 1000 = 6050 \, \text{mm}6.05m×1000=6050mm
✅ Answer: 6050 mm
3. Convert 56.0 kilograms into milligrams.
1 kilogram = 1,000,000 milligrams56.0 kg×1,000,000=56,000,000 mg56.0 \, \text{kg} \times 1,000,000 = 56,000,000 \, \text{mg}56.0kg×1,000,000=56,000,000mg
✅ Answer: 56,000,000 mg
4. How many nanometers are there in 2.5 meters?
1 meter = 1,000,000,000 nanometers2.5 m×1,000,000,000=2,500,000,000 nm2.5 \, \text{m} \times 1,000,000,000 = 2,500,000,000 \, \text{nm}2.5m×1,000,000,000=2,500,000,000nm
✅ Answer: 2,500,000,000 nm
5. Convert 180.4 milliliters into liters.
1 liter = 1000 milliliters180.4 mL÷1000=0.1804 L180.4 \, \text{mL} \div 1000 = 0.1804 \, \text{L}180.4mL÷1000=0.1804L
✅ Answer: 0.1804 L
6. How many feet are there in 387.5 cm?
Use:
- 1 inch = 2.54 cm
- 1 foot = 12 inches
First convert cm to inches:387.5÷2.54=152.56 inches387.5 \div 2.54 = 152.56 \, \text{inches}387.5÷2.54=152.56inches
Then convert inches to feet:152.56÷12=12.71 feet152.56 \div 12 = 12.71 \, \text{feet}152.56÷12=12.71feet
✅ Answer: 12.71 feet
7. Michael Jordan’s height: 6 feet 6 inches
First convert to inches:(6×12)+6=72+6=78 inches(6 \times 12) + 6 = 72 + 6 = 78 \, \text{inches}(6×12)+6=72+6=78inches
Then convert inches to cm:78×2.54=198.12 cm78 \times 2.54 = 198.12 \, \text{cm}78×2.54=198.12cm
Convert cm to meters:198.12÷100=1.9812 m198.12 \div 100 = 1.9812 \, \text{m}198.12÷100=1.9812m
✅ Answer: 198.12 cm or 1.9812 meters
8. Convert 56 pounds to kilograms
1 kilogram = 2.2 pounds56÷2.2=25.45 kg56 \div 2.2 = 25.45 \, \text{kg}56÷2.2=25.45kg
✅ Answer: 25.45 kg
📘 Textbook-Style Explanation (Approx. 300 Words)
Unit conversions are essential in science and everyday life. The metric system uses base-10 units, which simplifies the conversion process by using powers of ten. For example, converting meters to centimeters or millimeters just involves multiplying by 100 or 1000, respectively. Similarly, converting between liters and milliliters or kilograms and milligrams uses these same patterns of scale.
When converting from metric to imperial units (such as from centimeters to feet), you must use given conversion factors, such as 2.54 cm per inch and 12 inches per foot. This typically involves a two-step conversion: first converting to inches, then to feet.
Mass conversions between systems, such as pounds to kilograms, require division or multiplication by a fixed ratio (e.g., 2.2 lbs = 1 kg). Understanding these conversions allows for better comparison and understanding of measurements across different contexts and countries.
In real-life applications, such as sports or agriculture, precise conversions can help describe athlete stats or product weights in different systems. For example, Michael Jordan’s height can be expressed in centimeters or meters for international comparisons. Similarly, converting the weight of a bushel of corn from pounds to kilograms is crucial for scientific and trade purposes.
Ultimately, mastering unit conversions helps bridge global measurement standards and supports accurate scientific communication, travel, health care, and commerce.
