Physical Quantities and their Measurement

Fundamental Units

Fundamental units are not derived from one another; also they are not resolved into any further units. There are a total of seven fundamental units of the S. I. system including:

Physical Quantity Unit Name Unit Symbol
Time Second \operatorename { S}
Mass Kilogram \operatorename { kg }
Length Meter \operatorename { M}
Temperature Kelvin \operatorename { K }
Electric Current Ampere \operatorename { A }
Luminous Intensity Candela \operatorename { cd}
Amount of Substance Mole \operatorename { Mol }

Derived Units

These units are a function of more than one fundamental units:

Quantity with Symbol Unit (S.I.) Symbol
Velocity (v) Meter per sec  \operatorname{ms}^{-1}
Area (A) Square Meter  \operatorname{m}^{2}
Volume (V) Cubic Meter \operatorname{m}^{3}
Density (d) Kilogram m^{-3} \operatorname{Kg m}^{-3}
Force (F) Newton (N) \operatorname{Kg ms}^{-2}
Energy (E) Joule (J) \operatorname{Kg} \operatorname{m^2s}^{-2}

Measurement of Temperature

There are mainly three scales of temperature.

  1. Kelvin Scale (K)
  2.  Degree Celcius Scale  (^oC)
  3. Degree Fahrenheit Scale   (^oF)

Relations

^oF=\dfrac{9}{5} (^oC) +32

 ^oK= ^oC+273

 0 \text { K temp} = \text { Absolute Zero }

Kelvin Scale is the most use temperature scale in Chemistry.
