For the metric system, it is the modern form and contains coherent system for the measuring units. It is based on seven base units along with a set of twenty prefixes which are used to specify the multiples and fractions of the base units.

Answer to Problem 6.1Q

The seven base units for the SI metric system are meter, kilogram, second, kelvin, ampere, candela, and mole.

Explanation of Solution

The seven base units of the SI metric system are written below along with the quantities for which they are used and the symbols which are used to represent these units.

Quantity	Base Unit	Symbol
1. Length	meter	m
2. Mass	kilogram	kg
3. Time	second	s
4. Thermodynamic temperature	kelvin	K
5. Electric current	ampere	A
6. Luminous intensity	candela	cd
7. Amount of substance	mole	mol

For additional measurements, these base units are combined as required to derive the necessary units.
