Energy Conversion
Enter a number into Energy, select its unit in Unit, and press Convert. The matching values show up in cards beneath the button.
What this energy converter does
Enter a number into Energy and choose its unit in Unit from Watt-hour (Wh), Kilowatt-hour (kWh), Megawatt-hour (MWh), BTU (IT) (BTU), kiloBTU (IT) (kBTU), Joule (J), Kilojoule (kJ), Megajoule (MJ) or Gigajoule (GJ). Press Convert to see the results.
The form computes only when the button is pressed. Results appear in nine cards below the button. Copy writes a result and its unit to the clipboard. Clear resets the form. Everything runs in the browser and nothing is uploaded.
For example, entering Energy: 1 and Unit: Kilowatt-hour (kWh) returns nine cards including Watt-hour: 1000 Wh, Kilowatt-hour: 1 kWh, Megawatt-hour: 0.001 MWh, BTU (IT): 3412.14163312794 BTU, kiloBTU (IT): 3.41214163312794 kBTU, Joule: 3600000 J, Kilojoule: 3600 kJ, Megajoule: 3.6 MJ and Gigajoule: 0.0036 GJ.
Energy conversion formula
The three hour-based units sit a factor of one thousand apart: 1 kWh reads as 1000 Wh and 0.001 MWh, while 1 MWh reads as 1000000 Wh and 1000 kWh. Going the other way, 1 Wh reads as 0.001 kWh and 0.000001 MWh.
For the British thermal units, entering Energy: 1 with Unit: BTU (IT) (BTU) returns nine cards including Watt-hour: 0.293071070172222 Wh, Kilowatt-hour: 0.000293071070172222 kWh, Megawatt-hour: 0.000000293071070172222 MWh and BTU (IT): 1 BTU. With Unit: kiloBTU (IT) (kBTU), the cards include Watt-hour: 293.071070172222 Wh, Kilowatt-hour: 0.293071070172222 kWh, Megawatt-hour: 0.000293071070172222 MWh and BTU (IT): 1000 BTU.
The joule units line up similarly. Entering Energy: 1000 with Unit: Joule (J) returns nine cards including Watt-hour: 0.277777777777778 Wh, Kilowatt-hour: 0.000277777777777778 kWh, Megawatt-hour: 0.000000277777777777778 MWh, BTU (IT): 0.947817120313317 BTU, kiloBTU (IT): 0.000947817120313317 kBTU, Joule: 1000 J, Kilojoule: 1 kJ, Megajoule: 0.001 MJ and Gigajoule: 0.000001 GJ.
