Time is a common term for the experience of duration and a fundamental quantity of measuring systems.
Thus, similar to the definition of other fundamental quantities (like time and mass), space is defined via measurement.
On the other hand, it can be related to other fundamental quantities.
The graph can be used to calculate fundamental quantities.
Further, the scalar potential is the fundamental quantity in quantum mechanics.
This is the fundamental quantity from which the world's weather/climate system obtains it energy.
In the metric system and other recent systems, a single basic unit is used for each fundamental quantity.
It admits time as a fundamental quantity, but only in a restricted way.
This is because the fundamental physical quantities involved within each of these examples are related through first and second order derivatives.
Many other fundamental quantities in science are time derivatives of one another:
