Joules (J) to Kilowatt-hours (kWh) Converter

The Conversion Formula

The formula for converting joules (J) to kilowatt-hours (kWh) is:

\[kWh = \frac{J}{3,600,000}\]

Where:

• kWh: Kilowatt-hours
• J: Joules

Conversion Steps

1. Start with the number of joules you want to convert
2. Divide this number by 3,600,000
3. The result is the equivalent number of kilowatt-hours

Example Conversion

Let's convert 3,600,000 joules to kilowatt-hours:

\[kWh = \frac{3,600,000 J}{3,600,000} = 1 kWh\]

About Joules and Kilowatt-hours

The joule (J) and kilowatt-hour (kWh) are both units of energy, but they are used in different contexts:

• 1 joule is defined as the amount of energy transferred when a force of 1 newton acts over a distance of 1 meter.
• 1 kilowatt-hour is the amount of energy consumed by a 1-kilowatt appliance running for 1 hour.
• 1 kilowatt-hour is equal to 3,600,000 joules.

Kilowatt-hours are commonly used for measuring electrical energy consumption in households and industries, while joules are more often used in scientific calculations and for smaller quantities of energy.
