numerical value of magnitude of a physical quantity is
Physical quantity A physical quantity is a physical property of a phenomenon, body, or substance, that can be quantified by measurement or we can say that quantities which we come across during our scientific studies are called as the physical quantities.[1] A physical quantity can be expressed as the combination of a magnitude expressed by a number – usually a real number – and a unit:   n u  {\textstyle nu}  where   n  {\textstyle n}  is the magnitude and   u  {\textstyle u}  is the unit. For example, 6973167492749999999♠1.6749275×10−27 kg (the mass of the neutron), or 7008299792458000000♠299792458 metres per second (the speed of light). The same physical quantity   x  {\textstyle x}  can be represented equivalently in many unit systems, i.e.   x = n 1  u 1  = n 2  u 2   {\textstyle x=n_{1}u_{1}=n_{2}u_{2}} .
Corona Spectroscopy measurements indicate strong ionization and plasma temperature in excess of 1,000,000 kelvins,[1] much hotter than the surface of the Sun.
Standard deviation This means that the standard deviation is equal to the square root of the difference between the average of the squares of the values and the square of the average value. See computational formula for the variance for proof, and for an analogous result for the sample standard deviation.
Inertia Inertia is the resistance of any physical object to any change in its state of motion. This includes changes to the object's speed, direction, or state of rest.
