The Percent Change in Area calculator computes the change in area between an initial area (Ai) and a final area (Af).
INSTRUCTIONS: Choose units and enter the following:
% Reductions in Area: The calculator returns the percentage change.
PC = (Af - Ai)/Ai
Percent reduction in area is often used in other engineering equations for stress and strain. The equation takes as input the initial area and the changed area to calculate and return the delta change in the area.
When the change in area is due to deforming strain applied to solids, there is no negative value for this concept. No strain results in an expansion of the material.
The calculator automatically handles numerous area units. With this feature you can compute the reduction in area with different units. The initial area can be 5.3 square yards, and the final area be 4.2 square meters, and the calculator accurately will provide an answer of 5.22% reduction in area.
