Metric Conversions for TEAS 7

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.

Correct Answer: B

Rationale: The correct answer is B: 0.1 cm. 1 millimeter is equal to 0.1 centimeters because there are 10 millimeters in 1 centimeter. To convert millimeters to centimeters, you divide by 10. Choice A (1/100 cm) is incorrect because 1 millimeter is not equal to 1/100 of a centimeter. Choice C (1 cm) is incorrect because 1 millimeter is smaller than 1 centimeter. Choice D (10 cm) is incorrect because 1 millimeter is not equal to 10 centimeters; it is only 0.1 centimeters.

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.

Correct Answer: A

Rationale: To convert liters to milliliters, you multiply by 1000 since 1 liter = 1000 ml. Therefore, 0.5 liters x 1000 = 500 ml. Thus, the correct answer is A (500 ml). Choice B (50 ml) is incorrect as it is 10 times smaller than the correct answer. Choice C (5 ml) is incorrect as it is 100 times smaller than the correct answer. Choice D (0.5 ml) is incorrect as it is the same value in milliliters, not the conversion of liters to milliliters.

Correct Answer: C

Rationale: The correct answer is C: 1,000 grams. There are 1,000 grams in 1 kilogram because the prefix "kilo-" in the metric system signifies 1,000. Therefore, 1 kilogram equals 1,000 grams. Choice A (10 grams) is incorrect because it is not equivalent to a kilogram. Choice B (100 grams) is incorrect as well, as it is also not the correct conversion. Choice D (10,000 grams) is incorrect because it is ten times the amount in a kilogram.
