kWh to Joules Conversion: A Comprehensive Guide

Introduction

Energy is an essential part of our daily lives. We use it to power our homes, businesses, and vehicles. One common unit of energy is the kilowatt-hour (kWh). Another common unit of energy is the joule (J). In this article, we will explore the conversion between kWh and J.

Definitions

• Kilowatt-hour (kWh): A unit of energy equal to the amount of energy used by a 1-kilowatt device running for one hour.
• Joule (J): The SI unit of energy. It is defined as the amount of energy transferred or work done when a force of one newton is applied over a distance of one meter.

Conversion Factor

The conversion factor between kWh and J is:

1 kWh = 3,600,000 J

This means that one kilowatt-hour is equal to 3,600,000 joules.

Examples

Let's look at a few examples of kWh to J conversions:

• Example 1: Convert 5 kWh to J.

5 kWh x 3,600,000 J/kWh = 18,000,000 J

• Example 2: Convert 100 J to kWh.

100 J / 3,600,000 J/kWh = 0.00002778 kWh

Applications

The conversion between kWh and J is used in a wide
