Metric Conversions for TEAS 7 Questions

Question 1 of 5

What is 0.1 mg to mcg?

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.

Question 2 of 5

How many feet are equal to 1 yard?

Correct Answer: B

Rationale: To convert yards to feet, we use the fact that 1 yard is equal to 3 feet. This is because 1 yard is defined as 3 feet. Therefore, the correct answer is B: 3 feet. Explanation for other choices: A: 4 feet - Incorrect because 1 yard is equal to 3 feet, not 4 feet. C: 2 feet - Incorrect because 1 yard is equal to 3 feet, not 2 feet. D: 5 feet - Incorrect because 1 yard is equal to 3 feet, not 5 feet.

Question 3 of 5

Convert 0.75 kilograms to grams.

Correct Answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since 1 kilogram is equal to 1000 grams. So, 0.75 kg * 1000 = 750 grams. Therefore, choice B (750 grams) is correct. Choice A (75 grams) is incorrect as it is a decimal point off; choice C (7,500 grams) is incorrect as it is off by a factor of 10; and choice D (75,000 grams) is incorrect as it is off by a factor of 100.

Question 4 of 5

Convert 5,000 milligrams to grams.

Correct Answer: B

Rationale: To convert milligrams to grams, we divide by 1000 since there are 1000 milligrams in a gram. Therefore, 5,000 mg ÷ 1000 = 5 grams. Choice B is correct. Choice A (50 grams) is incorrect as it is 10 times the correct answer. Choice C (500 grams) is incorrect as it is 100 times the correct answer. Choice D (0.05 grams) is incorrect as it is 100 times less than the correct answer.

Question 5 of 5

Convert 0.20 liters to milliliters. What is the equivalent volume?

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.
