# Joules to Kilowatt-hours Converter

Enter a value in joules to get its equivalent in kilowatt-hours. Use the inverse button to switch conversion direction.

## Input data

- **Joules** - type: number; default: 1; step: 0.01

## How it works

kWh = J ÷ 3600000.

## Quick examples

- **1 J → 0 kWh** - Joules: 1
- **5 J → 0.000001 kWh** - Joules: 5
- **1000000 J → 0.277778 kWh** - Joules: 1000000

## Understanding your result

The result expresses the value entered in joules as kilowatt-hours. A kilowatt-hour measures energy, not power. One kWh is the energy used by one kilowatt over one hour.
