Question

What is the base metric unit for length, mass, volume, and temperature? Give a comparable measurement for each.

A) Length: Meter, Mass: Gram, Volume: Liter, Temperature: Celsius.
B) Length: Centimeter, Mass: Kilogram, Volume: Milliliter, Temperature: Fahrenheit.
C) Length: Kilometer, Mass: Milligram, Volume: Milliliter, Temperature: Kelvin.
D) Length: Decimeter, Mass: Microgram, Volume: Microliter, Temperature: Rankine.

Answer 1

The base metric units of measurement in the SI system for length is meter, for mass is kilogram, for volume is liter (for liquids) or cubic meter, and for temperature is Kelvin.

Step-by-step explanation:

The base metric units for length, mass, volume, and temperature in the International System of Units (SI) are as follows:

• Length: The base unit for length is the meter (m).
• Mass: The base unit for mass is the kilogram (kg).
• Volume: Volume is a derived unit based on the meter, where a cubic meter (m³) is the volume of a cube with sides of one meter in length. However, for liquid volumes, the liter (L) is commonly used, which is equal to one cubic decimeter (dm³).
• Temperature: The base unit for temperature is the Kelvin (K).

Therefore, the correct option that lists the base units is:

1. Length: Meter
2. Mass: Kilogram
3. Volume: Liter
4. Temperature: Kelvin

Comparable measurements in these units can be:

• A room's width might be 5 meters.
• A bag of sugar may have a mass of 1 kilogram.
• A bottle of soda might contain 2 liters.
• The boiling point of water is 373.15 Kelvin.
