Convert psig to Torr with Ease: A Comprehensive Guide

Introduction

Pressure is a fundamental physical quantity that plays a crucial role in various scientific and engineering applications. Understanding pressure units is essential for accurate measurements and data analysis. Two commonly used pressure units are pounds per square inch gauge (psig) and Torr (Torr). This article provides a comprehensive guide on converting psig to Torr, enabling you to seamlessly navigate between these units.

Understanding psig and Torr

Pounds per Square Inch Gauge (psig)

psig is a pressure unit that measures the pressure above atmospheric pressure. It is commonly used in industrial and engineering applications, where measurements are made relative to the surrounding atmospheric pressure.

Torr

Torr, also known as the millimeter of mercury (mmHg), is a unit of pressure defined as 1/760 of the standard atmospheric pressure at sea level. It is widely used in scientific and laboratory settings, particularly in vacuum technology and measurements involving low pressures.

Conversion Factors

To convert psig to Torr, the following formula is used:

Torr = psig x 51.715

Example: Convert 15 psig to Torr.

Torr = 15 psig x 51.715
= 775.725 Torr

To convert Torr to psig, the following formula is used:

psig = Torr / 51.715

Example: Convert 600 Torr to psig.

psig = 600 Torr / 51.715
= 11.602 psig

Conversion Table

For quick reference, the following table provides a conversion chart for psig to Torr:

Applications of psig and Torr

psig
