Accepted Answer

Kilogram (kg)

Answer

The kilogram (kg) is the standard base unit for measuring mass in the International System of Units (SI), which is the modern form of the metric system. It is a fundamental unit used globally in science, industry, and commerce. While grams are also used, the kilogram serves as the primary reference for mass.

Question 2

How many millimeters are in one centimeter?

Accepted Answer

10 mm

Answer

The metric system is based on powers of ten, making conversions straightforward. One centimeter (cm) is equal to 10 millimeters (mm). This relationship is fundamental to understanding linear measurements within the metric system.

Question 3

What is the metric unit for temperature?

Accepted Answer

Celsius (°C)

Answer

Celsius (°C) is the most commonly used metric unit for measuring temperature in most parts of the world. While Kelvin (K) is the SI base unit for thermodynamic temperature, Celsius is widely adopted for everyday use and many scientific applications. It defines the freezing point of water as 0°C and the boiling point as 100°C.

Question 4

Which of the following is the conversion factor from kilometers to miles?

Accepted Answer

0.621371 miles

Answer

The conversion factor from kilometers to miles is approximately 0.621371 miles per kilometer. This specific value is used to accurately translate distances between the metric system (kilometers) and the imperial system (miles). Knowing this factor is crucial for international communication and applications where both systems are used.

Question 5

Which metric unit is used to measure volume?

Accepted Answer

Liter (L)

Answer

The liter (L) is the standard metric unit used to measure volume, particularly for liquids and gases.
