Final answer:
The base units in the international system (SI) of units are Meter (m) for length, Kilogram (kg) for mass, and Second (s) for time. The SI system also includes other base units like Ampere, Kelvin, mole, and candela.
Step-by-step explanation:
The base units in the international system (SI) of units include the Meter (m) for length, the Kilogram (kg) for mass and the Second (s) for time. These three units form the foundation of the SI system, which is the modern form of the metric system and is the most widely used system of measurement around the world. Other base units in the SI system are Ampere (A) for electric current, Kelvin (K) for thermodynamic temperature, mole (mol) for amount of substance, and candela (cd) for luminous intensity.
