Energy density unit conversion (by weight)_Online Calculator



Energy unit conversion calculator (by weight)

Commonly used energy units are: Joule (J), kWh (kwh), card (cal), kcal, degree. Commonly used power units: watts, kilowatts, cold tons, horses.

1 joule = 1 watt second

1 kWh = 1000 watts * 3600 seconds = 3600 kilojoules, ie 1 kW = 3600 kJ / hr

1 kWh = 8.6 * 10 5 card

1 big card = 1000 cards

1 card indicates the amount of heat absorbed by one gram of water when it is raised by one degree Celsius, which is approximately equal to 4.2 joules.

1 kWh = 861 kcal

Once = 861 big card

1 US cold tons = 3024 kcal / hour (kcal / h) = 3.517 kilowatts (KW)

1 Japan cold tons = 3320 kcal / hour (kcal / h) = 3.861 kilowatts (KW)

(Note: 1 cold ton is the amount of refrigeration required to make 1 ton of 0 ° C water into 0 ° C of ice in 24 hours.) The calorific value of natural gas per cubic combustion is 8,000 kcal to 8500 kcal 1 cubic natural gas = 9.29 Degree ~ 9.9 degrees

1 horse = 1 horsepower = 735 watts
