Pascals to PSI: A Comprehensive Conversion Guide

Introduction

Pascals (Pa) and pounds per square inch (psi) are two units of measurement commonly used to quantify pressure. Pascals are the standard unit of pressure in the International System of Units (SI), while psi is commonly used in engineering and industry in the United States and other countries. Understanding the conversion between these units is essential for accurate calculations and data analysis.

Conversion Formula and Example

The conversion formula for pascals to psi is:

1 Pa = 0.000145037738 psi

To convert pascals to psi, simply multiply the pascal value by 0.000145037738.

Example:

Convert 100,000 Pa to psi:

100,000 Pa x 0.000145037738 psi = 14.5037738 psi
