STATEMENT 1 When the unit for measurement of a quantity is changed, its numerical value changes STATEMENT 2 Smaller the unit of measurement matter is its numerical value

A : When we change the unit of a measurement of a quantity, its numerical value changes. R : The product of numerical value of the physical quantity and unit for a quantity remain constant.

If u_1 and u_2 are the units selected in two systems of measurement and n_1 and n_2 their numerical values, then

If u_(1) and u_(2) are the units selected in two systems of measurement and n_(1) and n_(2) their numerical values, then

Statement-1: The coefficient of thermal expansion of a body measured in (.^(@)F)^(-1) is numerically smaller than that measured in .^(@)C^(-1) . Statement-2: Fahrenheit is a smaller unit than centigrade.
