1. How many millimeters are in 5 centimeters?

• A. 50 mm
• B. 500 mm
• C. 5 mm
• D. 500 cm

Correct answer: B

Rationale: To convert centimeters to millimeters, you multiply by 10 since there are 10 millimeters in a centimeter. Therefore, 5 centimeters x 10 = 50 millimeters, making choice A the correct answer. Choice C, '5 mm,' is incorrect as it represents the original quantity in millimeters. Choice D, '500 cm,' is incorrect as it converts the centimeters to centimeters instead of millimeters.

2. What is the equivalent of 0.3 mg in mcg?

• A. 300 mcg
• B. 30 mcg
• C. 3000 mcg
• D. 3 mcg

Correct answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000 since 1 mg is equal to 1000 mcg. Therefore, 0.3 mg x 1000 = 300 mcg. This conversion is crucial in healthcare to ensure accurate medication dosages. Choice B (30 mcg) is incorrect as it represents the conversion of 0.03 mg to mcg. Choice C (3000 mcg) is incorrect as it is the result of multiplying 0.3 mg by 10 instead of 1000. Choice D (3 mcg) is incorrect as it is the result of not multiplying by 1000 to convert milligrams to micrograms.

3. What is the value of one femtometer (fm) in meters?

• A. 10^-15 meters
• B. 10^-9 meters
• C. 10^-12 meters
• D. 10^-18 meters

Correct answer: A

Rationale: A femtometer is equivalent to 10^-15 meters. The prefix 'femto-' signifies a factor of one quadrillionth (10^-15), making choice A the correct answer. Choice B (10^-9 meters) represents a nanometer, not a femtometer. Choice C (10^-12 meters) corresponds to a picometer, not a femtometer. Choice D (10^-18 meters) is even smaller than a femtometer and refers to an attometer, not a femtometer.

4. How many grams are in one kilogram?

• A. 100 grams
• B. 1000 grams
• C. 500 grams
• D. 2000 grams

Correct answer: B

Rationale: The correct answer is B: 1000 grams. This is because by definition, 1 kilogram is equal to 1000 grams. Choice A, 100 grams, is incorrect as it underestimates the actual conversion. Choice C, 500 grams, and Choice D, 2000 grams, are also incorrect as they do not align with the correct conversion factor of 1 kilogram to 1000 grams.

5. What is 0.5 liter in ounces?

• A. 16.91 oz
• B. 15.91 oz
• C. 17.91 oz
• D. 18.91 oz

Correct answer: A

Rationale: To convert liters to ounces, you need to multiply the liter value by 33.814. Therefore, to convert 0.5 liters to ounces, you would calculate 0.5 x 33.814 = 16.91 ounces. This conversion factor is commonly used in cooking and liquid measurements. Choice B, C, and D are incorrect as they do not reflect the accurate conversion from liters to ounces.
