A:### Quick Answer

The psi, or pounds per square inch, is a unit of pressure (P) using the foot-pound-second (FPS) system. To calculate psi, divide the force applied (F) with the area (A).

Know More**Measure the force applied**Use an instrument such as a force gauge, spring scale or strain gauge. Make sure that the unit is in pounds. Convert the value if necessary.

**Measure the total area on which force is applied**Measure the length and the width, and make sure that both values use the same unit, in this case inches, you can proceed to multiply them.

**Calculate the pressure in psi**Divide the measured force (in pounds) with the measure area (in square inches).

## How do you calculate exponential growth and decay?

A:Exponential growth and decay can be determined with the following equation: N = (NI)(e^kt). In this equation, "N" refers to the final population, "NI" is the starting population, "t" is the time over which the growth or decay took place and the "k" represents the growth or decay constant. If necessary, this equation may be rearranged to find any of these variables.
