Key Stage 5
Meaning
Base units are the fundamental units that define the SI system.
About Base Units
- There are seven base units in the International System of Units (SI): metre (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol), and candela (cd).
- Base units are the foundation for all other units in the SI system, known as derived units.
- They provide a standardized way of measuring physical quantities.
- The SI system is used globally for scientific and technical measurements.
- Accurate definitions of base units are essential for consistency in measurements across different fields of science.
- Base units are defined by fundamental physical constants and universal properties.
