A magnitude is a number and so has no units.
A magnitude is a pure number - with no SI unit.
The unit vector itself does not have a specific SI unit because it is a dimensionless quantity. A unit vector is defined as a vector with a magnitude of one, used to indicate direction. It is typically represented as a normalized form of a vector, retaining the direction while discarding the magnitude. Therefore, it is expressed in the same units as the original vector from which it is derived, but the unit vector itself is simply a ratio and has no units.
The scale used is usually Celsius or Kelvin.AnswerThe SI unit of temperature is the kelvin (K). Celsius is a metric unit, but not an SI unit, although it may be 'used alongside' the SI system.
The official SI unit for mass is the kilogram.
SI units are used fundamentally.SI unit is used by everyone. Hence, it is a standard unit for measurement.
The SI unit used to measure a person's weight is the kilogram (kg).
The SI unit used to measure mass is kilograms. It is written as Kg.
The SI unit of temperature is Kelvin, but degrees Celsius is a derived SI unit for temperature and more commonly used.
The SI unit which is used to measure mass is the kilogram.
The SI unit of time is the "second".
the litre is the standard si unit for volume.
SI unit kilogram is used to measure mass. It is abbreviated as kg.
