The amount by which unit area of a material increases when the temperature is raised by one degree is called the coefficient of superficial (i.e. area) expansion and is represented by β (Greek beta).

Expansion in area of a Laminar surface due to heating is known as superficial expansion.
Let a1 = area of a surface
t1 = its initial temperature
a2 = area of the surface after heating
t2 = final temperature
The coefficient of superficial expansion is defined as the ratio of increase in area to its original area for every degree increase in temperature.
