Metric Conversions for TEAS 7

Correct Answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000 since 1 mg = 1000 mcg. Therefore, 0.3 mg would be equal to 0.3 * 1000 = 300 mcg. This makes choice A (300 mcg) the correct answer. Choices B, C, and D are incorrect because they do not apply the correct conversion factor of 1000 to convert from mg to mcg, leading to incorrect values.

Correct Answer: B

Rationale: To convert liters to milliliters, you multiply by 1000 since there are 1000 milliliters in 1 liter. So, 0.6 liters x 1000 ml = 600 ml. Choice B (600 ml) is correct. Choice A (60 ml) is incorrect as it is 10 times less. Choice C (6 ml) is incorrect as it is 100 times less. Choice D (6000 ml) is incorrect as it is 10 times more.

Correct Answer: A

Rationale: To convert 0.20 liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, 0.20 liters = 0.20 x 1000 = 200 milliliters. So, the correct answer is A: 200 ml. Choice B (20 ml) is incorrect as it represents 0.02 liters. Choice C (2 ml) is incorrect as it represents 0.002 liters. Choice D (2000 ml) is incorrect as it is the result of incorrectly multiplying 0.20 liters by 1000 twice.

Correct Answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you multiply by 1000. So, 0.1 mg x 1000 = 100 mcg, which is the correct answer (A). The other choices are incorrect because: B: 10 mcg - Incorrect, as it is the result of multiplying by 100, not 1000. C: 1000 mcg - Incorrect, as this is the equivalent of 1 mg, not 0.1 mg. D: 1 mcg - Incorrect, as it is the result of dividing by 1000, not multiplying.
