~The order of magnitude is the exponential change of plus or minus of the value or quantity of an object.

For example,

~ The speed of light is given as 3.00 × 10^8 m s-¹. So the order of magnitude of the speed of

light is 8. The order of magnitude, gives an estimate about the magnitude of the quantity.

~ If the charge on an electron is 1.6 × 10^-19 C. Therefore, we can say that the change possessed by an electron is of the order 10^-19on its order of magnitude is – 19.
