Psig to Torr: Unlocking the Secrets of Pressure Conversion

Introduction

Measuring pressure is essential for various scientific and industrial applications. Two common units of pressure are pounds per square inch gauge (psig) and torr. Understanding the conversion between these units is crucial for accurate analysis and measurement. This comprehensive article explores the conversion process, providing practical examples and insights into real-world applications.

Conversion Formula

The conversion formula from psig to torr is:

Torr = (Psig x 51.715) + 101325

Where:

• Torr is the pressure in torr
• Psig is the pressure in psig

Example Conversion

Suppose we want to convert 20 psig to torr. Using the conversion formula:

Torr = (20 x 51.715) + 101325
Torr = 1042.3 + 101325
Torr = 102367.3

Therefore, 20 psig is equivalent to 102367.3 torr.
