This guide helps you easily convert between various energy units used in physics, engineering, and everyday life. Whether you're working with clear, kilowatt-hours (kWh), watt-hours (Wh), megawatt-hours (MWh), British Thermal Units (BTU), kiloBTU (kBTU), joules (J), kilojoules (kJ), megajoules (MJ), or gigajoules (GJ), this tutorial provides the formulas and examples you need to make accurate conversions.
In the sections below, you will find detailed explanations and step-by-step examples for converting between different energy units.
Formula: Joule = Kilowatt-hour * 3,600,000
Example: Convert 5 Kilowatt-hours to Joules.
Solution: 5 kWh * 3,600,000 = 18,000,000 J
Formula: Joule = Watt-hour * 3600
Example: Convert 10 Watt-hours to Joules.
Solution: 10 Wh * 3600 = 36,000 J
Formula: Joule = Megawatt-hour * 3,600,000,000
Example: Convert 2 Megawatt-hours to Joules.
Solution: 2 MWh * 3,600,000,000 = 7,200,000,000 J
Formula: Joule = BTU * 1055.06
Example: Convert 1000 British Thermal Units to Joules.
Solution: 1000 BTU * 1055.06 = 1,055,060 J
Formula: Joule = KiloBTU * 1,055,060
Example: Convert 5 KiloBTU to Joules.
Solution: 5 kBTU * 1,055,060 = 5,275,300 J
Formula: Joule = Kilojoule * 1000
Example: Convert 200 Kilojoules to Joules.
Solution: 200 kJ * 1000 = 200,000 J
Formula: Joule = Megajoule * 1,000,000
Example: Convert 2 Megajoules to Joules.
Solution: 2 MJ * 1,000,000 = 2,000,000 J
Formula: Joule = Gigajoule * 1,000,000,000
Example: Convert 0.5 Gigajoules to Joules.
Solution: 0.5 GJ * 1,000,000,000 = 500,000,000 J
