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.

How physical quantity measurement of torr is related to si unit of torr?
The torr is a unit of pressure that is defined as 1/760 of an atmosphere, which is equivalent to 101325 pascals in SI units. Thus, 1 torr is approximately equal to 133.322 pascals (Pa). The torr is commonly used in various scientific and engineering applications, particularly in fields like vacuum measurement. While the SI unit of pressure is the pascal, the torr remains widely accepted and used alongside it.
What is the unit used for measurement for atmosphere pressure?
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
What is the si unit of quantity?
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.
Name the physical quantity whose SI unit is JC-1Is it a scalar or a vector quantity?
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.

What is the SI unit fro expressing the quantity?
There are different units for different quantities.
How is vacuum measured and what units are typically used for this measurement?
Vacuum is measured using a unit called Torr, which is commonly used in scientific and industrial settings. Another unit used for vacuum measurement is Pascal (Pa), which is the SI unit of pressure. Vacuum levels are typically expressed in Torr or Pa to indicate the degree of pressure below atmospheric pressure.
