Officials with the General Conference on Weights and Measures (CGPM) have announced that at a meeting to be held next week, four of the base units used in the metric system will be redefined. The four units under review are the ampere, kilogram, mole and kelvin.
What are the 7 basic units of measurement?
There are seven base units in the SI system:
- the kilogram (kg), for mass.
- the second (s), for time.
- the kelvin (K), for temperature.
- the ampere (A), for electric current.
- the mole (mol), for the amount of a substance.
- the candela (cd), for luminous intensity.
- the meter (m), for distance.
