What are SI units give an example?
The SI comprises a coherent system of units of measurement starting with seven base units, which are the second (symbol s, the unit of time), metre (m, length), kilogram (kg, mass), ampere (A, electric current), kelvin (K, thermodynamic temperature), mole (mol, amount of substance), and candela (cd, luminous intensity) …
Where are SI units used?
The six base units that they used were the metre, kilogram, second, ampere, Kelvin, and candela. The seventh base unit, the mole, was added in 1971. SI is now used almost everywhere in the world, except in the United States, Liberia and Myanmar, where the older imperial units are still widely used.

Degrees Celsius is a measurement of temperature, but is not an SI unit. The SI unit for temperature is Kelvin. Moles are the SI unit for amount of substance in terms of atoms. Ampere is the SI unit for current.
What are the different SI units?
The seven SI base units, which are comprised of:
- Length – meter (m)
- Time – second (s)
- Amount of substance – mole (mole)
- Electric current – ampere (A)
- Temperature – kelvin (K)
- Luminous intensity – candela (cd)
- Mass – kilogram (kg)
Are minutes SI units?
Although not an SI unit, the minute is accepted for use with SI units. The SI symbol for minute or minutes is min (without a dot). The prime symbol is also sometimes used informally to denote minutes of time.
What is the 10 different units used in measurement?
The base SI units are metre, kilogram, second, kelvin, ampere, candela and the mole and the three supplementary SI units are radian, steradian and becquerel. All other SI units can be derived from these base units.
