Metric Conversions for TEAS 7 Questions
Question 1 of 5
Convert 345 kilometers to meters (m).
Correct Answer: B
Rationale: To convert kilometers to meters, you multiply by 1000 since 1 kilometer is equal to 1000 meters. Therefore, 345 kilometers x 1000 = 345,000 meters. Choice A is incorrect as it doesn't account for the conversion factor. Choice C is incorrect as it adds an extra zero. Choice D is incorrect as it adds two extra zeros. Choice B is the correct answer as it correctly converts 345 kilometers to meters by multiplying by 1000.
Question 2 of 5
How many centimeters are in 1 meter?
Correct Answer: B
Rationale: The correct answer is B: 100 cm. There are 100 centimeters in 1 meter because the metric system is based on units of 10. 1 meter is equivalent to 100 centimeters as each meter is divided into 100 equal parts, which are centimeters. Choice A (10 cm) is incorrect as it represents the number of millimeters in a centimeter. Choice C (1,000 cm) is incorrect as it represents the number of millimeters in a meter. Choice D (10,000 cm) is incorrect as it is ten times the actual number of centimeters in a meter.
Question 3 of 5
What is equivalent to 1 L?
Correct Answer: D
Rationale: The correct answer is D: 1000 milliliters. 1 liter is equivalent to 1000 milliliters. This is because the metric system is based on the powers of 10, so there are 1000 milliliters in 1 liter. Choice A, 1 kilogram, is a unit of mass and not volume. Choice B, 1 quart, is a unit of volume but is not equivalent to 1 liter. Choice C, 1 milliliter, is much smaller than 1 liter, as it would take 1000 milliliters to make up 1 liter.
Question 4 of 5
What is 0.025 mg in mcg?
Correct Answer: A
Rationale: To convert mg to mcg, you need to multiply by 1000. Therefore, 0.025 mg x 1000 = 25 mcg. The correct answer is A (25 mcg). Choice B (250 mcg) is incorrect as it incorrectly multiplies by 10 instead of 1000. Choice C (2.5 mcg) is incorrect as it drops a zero from the conversion. Choice D (0.25 mcg) is incorrect as it adds an extra zero to the answer.
Question 5 of 5
Convert 250 milliliters to liters.
Correct Answer: B
Rationale: To convert milliliters to liters, we must divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 250 milliliters divided by 1000 equals 0.25 liters (choice B). Choice A is incorrect as it is 10 times the correct answer. Choice C is incorrect as it is 5 times the correct answer. Choice D is incorrect as it is 1/10th of the correct answer. Thus, the correct conversion is 0.25 liters.
