Energy Converter

Comprehensive Energy Converter

Energy plays a vital role in science, engineering, and everyday life. Our Energy Converter tool is designed to help you quickly and accurately convert energy values between various units. Whether you’re working with small-scale measurements in microjoules or tackling massive energy figures in kilowatt-hours or even gigaton equivalents, our tool covers it all.

What Energy Units Are Covered?

Our converter includes an extensive list of energy units with their conversion factors relative to the Joule (J), the SI base unit of energy. Here are some of the key units:

• Joule [J]
  The fundamental unit of energy in the International System of Units (SI).

• Metric Energy Units:

  • Kilojoule [kJ]: 1 kJ = 1000 J

  • Megajoule [MJ]: 1 MJ = 1,000,000 J

  • Gigajoule [GJ]: 1 GJ = 1,000,000,000 J

  • Millijoule [mJ], Microjoule [µJ], Nanojoule [nJ], Attojoule [aJ]

• Electrical and Mechanical Energy Units:

  • Kilowatt-hour [kW*h]: 1 kW*h = 3,600,000 J

  • Watt-hour [W*h]: 1 W*h = 3600 J

  • Kilowatt-second [kW*s] 和 Watt-second [W*s] (where 1 W*s = 1 J)

• Calorific Units:

  • Calorie (nutritional): 1 calorie (nutritional) = 4186.8 J

  • Calorie (IT) 和 Calorie (th) with values around 4.1868 J and 4.184 J respectively

  • Kilocalorie (IT) 和 Kilocalorie (th)

• British Thermal Units (Btu):

  • Btu (IT) 和 Btu (th) with conversion factors around 1055 J

  • Mega Btu (IT) for large-scale energy calculations

• Power and Energy Equivalents:

  • Horsepower hour [hp*h] 和 Horsepower (metric) hour

  • Gigawatt-hour [GW*h] 和 Megawatt-hour [MW*h]

• Particle and Atomic Scale Energy:

  • Electron-volt [eV], Kiloelectron-volt [keV], Megaelectron-volt [MeV]

  • Hartree energy 和 Rydberg constant

• Other Specialized Units:

  • Erg – commonly used in the field of physics

  • Fuel oil equivalent (in kiloliters and barrels)

  • Ton (explosives), Gigaton, Megaton和 Kiloton for large-scale energy estimates

  • Units based on force and distance, such as Newton meter [N*m], Pound-force foot [lbf*ft]和 Inch-pound [in*lbf]

转换器如何工作？

Our Energy Converter employs a two-step conversion process:

1. Convert to Joules:
   The tool first converts the input energy value into Joules using the corresponding conversion factor for the selected “From” unit.

2. Convert from Joules:
   It then converts the Joule value to the desired “To” unit using its conversion factor.

This method ensures precise and consistent conversions across a wide range of energy units.
