It isn't. There is no unit of quantity in the SI system.
Torr, historically was a unit of pressure, equal to one millimetre of Mercury. Equal nowadays to about 133.3 pascals.
The SI unit of quantity is the mole, denoted by the symbol "mol". It is used to measure the amount of substance present in a system.
These units are used:- pascal (Pa), the SI unit- millimetre of mercury- torr- millibar1 Pa = 1 N/m2 = 133,3224 mmHg = 7,506.10e-3 torr = 0,01 millibar
The physical quantity with the SI unit JC^-1 is the electric permittivity. It is a scalar quantity because it describes the ability of a material to store and transmit electrical energy.
The volume is measured in SI with litre (L) or millilitre (mL).
The SI unit for speed and velocity is meters per second (m/s). Speed is a scalar quantity that represents how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
The Pascal is the SI unit: one Newton per square meter. Other units are the atmosphere and the torr (760 torr/atm)
The SI unit for quantity of radioactive materials is Becquerel.The becquerel (symbol Bq) is the SI-derived unit of radioactivity.One Bq is defined as the activity of a quantity of radioactive material in which one nucleus decays per second.

The physical quantity is simply called area. The official unit (in SI) is the square meter.
The SI unit of electric charge is the Coulomb.
The volume is measured in SI with litre (L) or millilitre (mL).
There are different units for different quantities.
The SI unit for speed and velocity is meters per second (m/s). Speed is a scalar quantity that represents how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
