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: The correct answer is B: 2.54 cm. To convert inches to centimeters, we use the conversion factor 1 inch = 2.54 cm. This conversion factor is based on the definition of an inch and a centimeter. Therefore, 1 inch is equivalent to 2.54 centimeters. Choice A (1.54 cm) is incorrect as it is not the correct conversion factor for inches to centimeters. Choice C (3.54 cm) and Choice D (4.54 cm) are also incorrect as they do not correspond to the accurate conversion of inches to centimeters.

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 meters to kilometers, we divide by 1,000 since 1 kilometer is equal to 1,000 meters. Therefore, 1,000 meters divided by 1,000 equals 1 kilometer.

This would be the equivalent of 10 meters.
