Enter the total surface area (m^2) and the total mass (kg) into the Specific Surface Area Calculator. The calculator will evaluate the Specific Surface Area. 

Specific Surface Area Formula

The following two example problems outline the steps and information needed to calculate the Specific Surface Area.

SSA = SA / M
  • Where SSA is the Specific Surface Area (m^2/kg)
  • SA is the total surface area (m^2) 
  • M is the total mass (kg) 

To calculate the specific surface area, divide the total surface area by the mass.

How to Calculate Specific Surface Area?

The following example problems outline how to calculate Specific Surface Area.

Example Problem #1:

  1. First, determine the total surface area (m^2).
    • The total surface area (m^2) is given as: 150.
  2. Next, determine the total mass (kg).
    • The total mass (kg) is provided as: 3.
  3. Finally, calculate the Specific Surface Area using the equation above: 

SSA = SA / M

The values provided above are inserted into the equation below and computed.

SSA = 150 / 3 = 50.00 (m^2/kg)

Example Problem #2: 

For this problem, the variables required are provided below:

total surface area (m^2) = 160

total mass (kg) = 8

Test your knowledge using the equation and check your answer with the calculator..

SSA = SA / M = ?
