PSI Converter

The PSI Converter Tool is a comprehensive online pressure conversion calculator that helps you instantly convert between various pressure units. Whether you're an engineer, mechanic, scientist, student, or DIY enthusiast working with pressure measurements, this tool provides accurate conversions between PSI (pounds per square inch), kilopascals (kPa), bars, atmospheres (atm), millimeters of mercury (mmHg), megapascals (MPa), and torr.

What is a PSI Converter?

A PSI Converter is a specialized digital tool that enables quick and precise conversion between different pressure measurement units. PSI (pounds per square inch) is commonly used in the United States and other countries for measuring pressure in various applications including automotive tires, industrial systems, hydraulic equipment, and scuba diving tanks.

This converter uses internationally recognized conversion factors based on scientific standards. For example, 1 PSI = 6.89476 kPa and 1 bar = 14.5038 PSI. The tool automatically applies these precise factors, eliminating manual calculation errors and saving valuable time.

Examples

Example 1: Convert 32 PSI to kilopascals (common tire pressure)

Formula: 32 × 6.89476 = 220.63232 kPa

Example 2: Convert 2.5 Bar to PSI (industrial pressure conversion)

Formula: 2.5 × 14.5038 = 36.2595 PSI

Example 3: Convert 760 mmHg to PSI (standard atmospheric pressure)

Formula: 760 × 0.0193368 = 14.696 PSI (approximately 1 atmosphere)
