kg/cm2 to kPa Conversion: A Comprehensive Guide

Introduction

Kilograms per square centimeter (kg/cm2) and kilopascals (kPa) are two commonly used units of pressure. Understanding the conversion between these units is essential for various scientific, engineering, and industrial applications. This article provides a comprehensive guide to kg/cm2 to kPa conversion, addressing key concepts, conversion formulas, and practical use cases.

Key Concepts

Pressure: Pressure is the force applied perpendicularly over a given surface area.

kg/cm2: Kilograms per square centimeter is a unit of pressure where one kilogram of force is applied over one square centimeter of area.

kPa: Kilopascal is a unit of pressure in the International System of Units (SI), where one kilopascal is equivalent to one thousand newtons per square meter.

Conversion Formula

The conversion between kg/cm2 and kPa is straightforward:

1 kg/cm2 = 98.0665 kPa
1 kPa ≈ 0.010197 kg/cm2
