ExCPT Module 6: Calculations: Overview

What is the value of 1 gram (g) in milligrams (mg)?

• 1 gram (g) = 1,000 milligrams (mg)

• 1 gram (g) = 100 milligrams (mg)

• 1 gram (g) = 10 milligrams (mg)

• 1 gram (g) = 10,000 milligrams (mg)

Answer explanation

1 gram (g) is equal to 1,000 milligrams (mg) because the metric system is based on powers of ten, where 1 gram is 1,000 times larger than a milligram.

What is the value of 1 gram (g) in micrograms (mcg)?

• 1 gram (g) = 1,000,000 micrograms (mcg)

• 1 gram (g) = 10,000 micrograms (mcg)

• 1 gram (g) = 100,000 micrograms (mcg)

• 1 gram (g) = 1,000 micrograms (mcg)

Answer explanation

1 gram (g) is equal to 1,000 milligrams (mg), and each milligram is equal to 1,000 micrograms (mcg). Therefore, 1 gram equals 1,000 x 1,000 = 1,000,000 micrograms (mcg). Thus, the correct answer is 1 gram (g) = 1,000,000 micrograms (mcg).

How many grams (g) are in 1 kilogram (kg)?

• 1 kilogram (kg) = 1,000 grams (g)

• 1 kilogram (kg) = 100 grams (g)

• 1 kilogram (kg) = 10,000 grams (g)

• 1 kilogram (kg) = 10 grams (g)

Answer explanation

1 kilogram (kg) is equal to 1,000 grams (g). This is a standard conversion in the metric system, where 1 kg is defined as 1,000 g, making the first answer choice the correct one.

How many milliliters (mL) are in 1 liter (L)?

• 1 liter (L) = 1,000 milliliters (mL)

• 1 liter (L) = 100 milliliters (mL)

• 1 liter (L) = 10 milliliters (mL)

• 1 liter (L) = 10,000 milliliters (mL)

Answer explanation

1 liter (L) is equal to 1,000 milliliters (mL). This is a standard conversion in the metric system, making the first answer choice the correct one.

How many meters (m) are in 1 kilometer (km)?

• 1 kilometer (km) = 1,000 meters (m)

• 1 kilometer (km) = 100 meters (m)

• 1 kilometer (km) = 10,000 meters (m)

• 1 kilometer (km) = 10 meters (m)

Answer explanation

1 kilometer (km) is equal to 1,000 meters (m). This is a standard conversion in the metric system, where 1 km is defined as 1,000 m, making this the correct choice.

Which of the following is the base unit for length in the metric system?

• gram

• liter

• meter

• milliliter

Answer explanation

The base unit for length in the metric system is the meter. The gram is for mass, the liter for volume, and the milliliter is a smaller unit of volume. Therefore, the correct answer is meter.

Which of the following is the base unit for mass in the metric system?

• gram

• liter

• meter

• milliliter

Answer explanation

The base unit for mass in the metric system is the gram. Other options like liter and meter refer to volume and length, respectively, while milliliter is a smaller unit of volume.

Which of the following is the base unit for volume in the metric system?

• gram

• liter

• meter

• milliliter

Answer explanation

The base unit for volume in the metric system is the liter. It is used to measure liquids and is larger than a milliliter, which is a subunit of a liter. The gram measures mass, and the meter measures length.

Match the metric unit with its correct abbreviation:

• km

• L

• mL

• km

• L

• mL

• g

• g

Fill in the blank: The metric system uses increments of __ and decimals rather than fractions.

• 10

• 12

• 5

• 100

Answer explanation

The metric system is based on powers of 10, using increments of 10 and decimals for measurement. This makes calculations simpler compared to systems that use fractions, making 10 the correct choice.
