Metric Conversions for TEAS 7

Correct Answer: A

Rationale: The correct answer is A: kilogram. In the metric system, 'kg' stands for kilogram, which is the unit of mass. The prefix 'kilo-' denotes 1000, so a kilogram is equal to 1000 grams. This is the standard unit used to measure mass in the metric system. B: keg is incorrect as it is a container for storing liquids, not a unit of measurement. C: kroner is the currency used in Norway and Denmark, not a unit of measurement in the metric system. D: kraken is a mythical sea monster and not related to any unit of measurement. Therefore, the correct choice is A as it corresponds to the standard unit for mass in the metric system.

Correct Answer: B

Rationale: To convert milligrams to grams, you need to divide by 1000 since there are 1000 milligrams in 1 gram. Therefore, 35,400 mg divided by 1000 equals 35.4 grams. Choice B, 35.4 g, is the correct answer as it correctly represents the conversion. Choices A, C, and D are incorrect because they do not perform the correct conversion calculation. Choice A incorrectly moves the decimal point, choice C multiplies instead of divides, and choice D adds an extra zero.

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.

Correct Answer: C

Rationale: To convert from centimeters to millimeters, you multiply by 10 since there are 10 millimeters in 1 cm. Therefore, to find how many millimeters are in 0.75 cm, you multiply 0.75 by 10, which equals 7.5 mm. Therefore, the correct answer is C: 75 mm. Choice A: 7.5 mm is the result of the correct conversion. Choice B: 0.75 mm is incorrect as it's the original value, not the converted value. Choice D: 75 cm is incorrect as the question asks for millimeters, not centimeters.

Correct Answer: A

Rationale: To convert liters to milliliters, you multiply by 1000 because 1 liter is equal to 1000 milliliters. So, 0.5 liters x 1000 = 500 milliliters. Therefore, the correct answer is A: 500 milliliters. Choices B, C, and D are incorrect because they do not follow the correct conversion factor from liters to milliliters. B is too small, C is even smaller, and D is a decimal value that does not represent a proper conversion.
