Fundamental units, also known as base units, are the basic units of measurement that are used to define other units of measurement. They are considered to be the building blocks of the metric system and are used to measure physical quantities such as length, mass, time, electric current, temperature, and luminous intensity. There are seven fundamental units of measurement that are used in the International System of Units (SI):
1. Meter (m): for measuring length or distance
2. Kilogram (kg): for measuring mass
3. Second (s): for measuring time
4. Ampere (A): for measuring electric current
5. Kelvin (K): for measuring temperature
6. Mole (mol): for measuring the amount of substance

Fundamental units are the basic units of measurement that form the foundation of the International System of Units (SI). They are used to define all other units of measurement, and they are independent of any other units.
The SI defines seven fundamental units, which are:
Length - the meter (m)
Example: The length of a piece of paper can be measured in meters.
Mass - the kilogram (kg)
Example: The mass of a bag of flour can be measured in kilograms.
Time - the second (s)
Example: The time it takes to complete a race can be measured in seconds.
Electric current - the ampere (A)
Example: The amount of current flowing through an electrical circuit can be measured in amperes.
Temperature - the kelvin (K)
Example: The temperature of a room can be measured in kelvin.
Amount of substance - the mole (mol)
Example: The amount of a chemical substance in a solution can be measured in moles.
Luminous intensity - the candela (cd)
Example: The intensity of light emitted by a light bulb can be measured in candelas.
These fundamental units serve as the building blocks for all other units of measurement used in science, engineering, and everyday life. By defining these fundamental units and their relationships, the SI provides a common language for measurement that can be used across the world.

Examples of fundamental units include the meter for length, the kilogram for mass, the second for time, the ampere for electric current, the kelvin for temperature, the mole for the amount of a substance, and the candela for luminous intensity.
