Is 0.25 mg equal to 250 mcg?

Correct Answer: A

Rationale: The correct answer is A: TRUE. 0.25 mg is indeed equal to 250 mcg. This conversion is obtained by multiplying 0.25 mg by 1000 to convert it to micrograms. In pharmaceuticals, it is crucial to understand and convert between different dosage units accurately. Choice B is incorrect as the two quantities are equivalent. Choice C, 'Sometimes,' is misleading as the conversion from milligrams to micrograms follows a consistent ratio. Choice D, 'None of the above,' is incorrect as there is a definitive equivalence between the provided quantities.

Correct Answer: A

Rationale: The correct answer is 'millimeter' (A). 'mm' stands for millimeter, which is equal to one-thousandth of a meter. Choice B, 'megabyte,' is a unit of digital information storage, not a metric system unit. Choice C, 'millipede,' is an arthropod and not a metric unit. Choice D, 'metered,' is not a standard metric unit abbreviation.

Correct Answer: B

Rationale: The correct answer is B: 1000 meters. One kilometer is equivalent to 1000 meters. Therefore, 1000 meters is the accurate conversion from kilometers to meters. Choices A, C, and D are incorrect. Choice A (100 meters) is incorrect as it represents 1/10th of a kilometer. Choice C (500 meters) is incorrect as it is half the value of a kilometer. Choice D (2000 meters) is incorrect as it exceeds the value of a kilometer.

Correct Answer: A

Rationale: To convert 0.6 liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. Therefore, 0.6 liters equals 600 milliliters. Choice B (60 ml) is incorrect as it is a conversion of 0.06 liters, not 0.6 liters. Choice C (6 ml) is incorrect as it represents a conversion of 0.006 liters, not 0.6 liters. Choice D (0.6 ml) is incorrect as it is the original amount in milliliters, not the converted amount from liters.

Correct Answer: B

Rationale: The correct term for the amount of space an object occupies is 'volume.' Volume refers to the three-dimensional space that an object occupies and is measured in cubic units like cubic meters. 'Mass' (Choice A) refers to the amount of matter in an object, 'density' (Choice C) is the mass per unit volume of a substance, and 'area' (Choice D) is the measurement of the extent of a surface.

Correct Answer: A

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 1500 milliliters divided by 1000 equals 1.5 liters, making option A the correct answer. Option B, 0.15 liters, is incorrect as it would be the conversion of 150 milliliters. Option C, 15 liters, is incorrect because it would be the conversion of 15,000 milliliters. Option D, 0.015 liters, is incorrect as it would be the conversion of 15 milliliters.

Correct Answer: B

Rationale: To convert grams to kilograms, you divide by 1,000 since there are 1,000 grams in a kilogram. Therefore, 1,500 grams divided by 1,000 equals 1.5 kilograms, making choice B the correct answer. Choices A, C, and D are incorrect because they do not correctly convert grams to kilograms.

Correct Answer: A

Rationale: To convert liters to ounces, you need to multiply the volume in liters by 33.814. In this case, 0.5 liters multiplied by 33.814 equals approximately 16.91 ounces. This conversion is commonly used in culinary and liquid measurements. Choices B, C, and D are incorrect as they do not reflect the correct conversion factor from liters to ounces.

Correct Answer: D

Rationale: To convert pounds to kilograms, you need to divide the weight in pounds by 2.205 (1 kg = 2.205 lbs). Therefore, 255.0 pounds divided by 2.205 equals 115.6 kilograms. This results in choice D being the correct answer. Choices A, B, and C are incorrect as they do not reflect the accurate conversion calculation from pounds to kilograms.
