1. How many grams are in 1 kilogram?
- A. 10 grams
- B. 100 grams
- C. 1,000 grams
- D. 10,000 grams
Correct answer: C
Rationale: The correct answer is C: 1,000 grams. The metric system follows a logical conversion where 1 kilogram is equal to 1,000 grams. This conversion is a fundamental concept in understanding units of measurement. Choices A, B, and D are incorrect because they do not accurately reflect the conversion between kilograms and grams. Option A (10 grams) is incorrect as it represents 1/100th of the correct conversion. Option B (100 grams) is also incorrect as it represents 1/10th of the correct conversion. Option D (10,000 grams) is significantly higher than the actual conversion, making it incorrect. Understanding these basic unit conversions is essential for various fields where precise measurements are necessary.
2. Convert 0.6 liters to milliliters.
- A. 60 ml
- B. 600 ml
- C. 6 ml
- D. 6000 ml
Correct answer: B
Rationale: To convert 0.6 liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. 0.6 * 1000 = 600 ml, which is the correct answer. Choice A (60 ml) is incorrect because it represents 0.06 liters. Choice C (6 ml) is incorrect as it would be the milliliter equivalent for 0.006 liters. Choice D (6000 ml) is incorrect as it would be the milliliter equivalent for 6 liters.
3. How many cups are in one pint?
- A. 1 cup
- B. 2 cups
- C. 3 cups
- D. 4 cups
Correct answer: B
Rationale: One pint is equivalent to 2 cups. This conversion is a common measurement in cooking and baking. Choice A (1 cup), Choice C (3 cups), and Choice D (4 cups) are incorrect because a pint specifically contains 2 cups according to standard measurement conversions.
4. What is the correct conversion of 35,400 milligrams to grams (g)?
- A. 35.4 g
- B. 35.4 g
- C. 354 g
- D. 354,000 g
Correct answer: B
Rationale: To convert milligrams to grams, you need to divide by 1,000 because there are 1,000 milligrams in a gram. Therefore, 35,400 mg ÷ 1,000 = 35.4 grams. Choice A is incorrect because it does not account for the conversion from milligrams to grams. Choice C is incorrect as it incorrectly drops a zero, leading to an inaccurate conversion. Choice D is incorrect as it incorrectly multiplies instead of dividing, resulting in a significantly larger value than the correct answer.
5. Convert 34.5 grams to kilograms (kg).
- A. 3.45 kg
- B. 34.5 kg
- C. 345 kg
- D. 3.45 grams
Correct answer: A
Rationale: To convert grams to kilograms, divide by 1,000 since there are 1,000 grams in a kilogram. Therefore, 34.5 grams ÷ 1,000 = 0.0345 kilograms. The correct answer is 3.45 kg (not 3.45 grams, which is the amount given in the initial question). Choices B and C are incorrect as they do not involve the conversion from grams to kilograms. Choice D is also incorrect as it presents the value in grams instead of kilograms.
