Enter the mass (kg) and the ground contact area (m^2) into the calculator to determine the Ground Pressure (N/m^2). 

Ground Pressure (N/m^2) Formula

The following formula is used to calculate the Ground Pressure (N/m^2). 

GP = m * g / CA
  • Where GP is the Ground Pressure (N/m^2) (N/m^2)
  • m is the mass (kg) 
  • CA is the ground contact area (m^2) 
  • g is the acceleration due to gravity (9.81 m/s^2)

To calculate ground pressure, multiply the mass by the acceleration due to gravity, then divide by the ground contact area.

How to Calculate Ground Pressure (N/m^2)?

The following two example problems outline how to calculate the Ground Pressure (N/m^2).

Example Problem #1:

  1. First, determine the mass (kg). In this example, the mass (kg) is given as 43.
  2. Next, determine the ground contact area (m^2). For this problem, the ground contact area (m^2) is given as 30.
  3. Finally, calculate the Ground Pressure (N/m^2) using the equation above: 

GP = m * g / CA

Inserting the values from above and solving the equation: 

GP = 43 * 9.81 / 30 = 14.061 (N/m^2)

Example Problem #2: 

Using the same process as above, first define the variables required by the formula. In this case, these values are:

mass (kg) = 50

ground contact area (m^2) = 10

Entering these values yields:

GP = 50 * 9.81 / 10 = 49.05 (N/m^2)
