Formula Used in “PSIG to PSIA Converter”
When converting pressure readings from pounds per square inch gauge (PSIG) to pounds per square inch absolute (PSIA), the standard formula is:
PSIA = PSIG + 14.7
This formula accounts for atmospheric pressure, which is approximately 14.7 psi at sea level. Below, we will break down this formula for clarity.
Step-by-Step Breakdown of the Formula
To understand how to use the formula effectively, let’s break it down into its components:
- PSIG: This is the pressure reading measured above atmospheric pressure. It is often used in various industrial applications.
- 14.7: This constant represents the atmospheric pressure at sea level in psi. It is essential for converting gauge pressure to absolute pressure.
- PSIA: This is the absolute pressure, which reflects the total pressure including atmospheric pressure.
Example Calculation
To illustrate how to use the formula, let’s work through an example.
Inputs
| Input Type | Value |
|---|---|
| Pressure in PSIG | 30 |
Calculation Process
Using the formula:
- Identify the PSIG value: In this case, the PSIG is 30.
- Add atmospheric pressure: Use the constant 14.7.
- Perform the calculation: PSIA = 30 + 14.7
- Calculate: PSIA = 44.7
Output
| Output Type | Value |
|---|---|
| Pressure in PSIA | 44.7 |
From the above example, we can see that a pressure reading of 30 PSIG converts to 44.7 PSIA.
