Why are physical quantities expressed in order of magnitude your ans is
A physical quantity is a physical property of a material that can be quantified by measurement.[1] A physical quantity can be expressed as the combination of a magnitude expressed by a number – usually a real number – and a unit: {\textstyle nu} {\textstyle nu} where {\textstyle n} {\textstyle n} is the magnitude and {\textstyle u} {\textstyle u} is the unit. For example, 1.6749275×10−27 kg (the mass of the neutron), or 299792458 metres per second (the speed of light). The same physical quantity {\textstyle x} {\textstyle x} can be represented equivalently in many unit systems, i.e. {\textstyle x=n_{1}u_{1}=n_{2}u_{2}} {\textstyle x=n_{1}u_{1}=n_{2}u_{2}}.
Hi baby
The order of magnitude of a physical quantity is its magnitude in powers of ten when the physical quantity is expressed in powers of ten with one digit to the left of the decimal. Two numbers of the same order of magnitude have roughly the same scale- the larger value is less than ten times the smaller value.
