## Absolute Pressure Calculator

The Absolute Pressure Calculator is a handy tool used to calculate the absolute pressure of a gas or liquid. It works by summing up the gauge pressure and atmospheric pressure to give absolute pressure. This calculator is useful in various fields, such as physics, chemistry, and engineering, where pressure measurement is crucial.

## How Does the Calculator Work?

The Absolute Pressure Calculator works based on a simple formula. To calculate the absolute pressure, the atmospheric pressure and gauge pressure are added together. Gauge pressure is the pressure measured by a gauge relative to the atmospheric pressure, while atmospheric pressure is the pressure exerted by the earth’s atmosphere on objects on its surface. Therefore, the formula for calculating absolute pressure is:

`Absolute Pressure = Atmospheric Pressure + Gauge Pressure`

This formula is used by the Absolute Pressure Calculator to calculate the absolute pressure based on the input of atmospheric pressure and gauge pressure.

## Examples of Absolute Pressure Calculation

To demonstrate how the Absolute Pressure Calculator works, here are a few examples of calculating absolute pressure:

Example 1:

```
Atmospheric pressure = 101.325 kPa
Gauge pressure = 100 kPa
Absolute pressure = 101.325 kPa + 100 kPa = 201.325 kPa
```

Example 2:

```
Atmospheric pressure = 14.7 psi
Gauge pressure = 20 psi
Absolute pressure = 14.7 psi + 20 psi = 34.7 psi
```
