Joules (J) to kilocalories (kcal) energy conversion calculator and how to convert.
Enter the energy in joules and press the Convert button:
2 kcalth = 4184 J
joules to kilocalories using the formula above. This energy in joules E(J) is equal to the energy in kilocalories E(kcal-th) divided by 4184:
E(kcal) = E(J) / 4184
Convert 7000 joules to kilocalories.
E(kcal) = 7000 J / 4184 = 1.6730 kcal
Convert 8000 joules to kilocalories.
E(kcal) = 8000 J / 4184 = 1.9120 kcal
Convert 18000 joules to kilocalories.
E(kcal) = 18000 J / 4184 = 4.3021 kcal
2 kcalIT = 4186.8 J
Energy in joules E(J) equals energy in international kilocalories E(kcal-IT) divided by 4186.8:
E(kcal-IT) = E(J) / 4186.8
Convert 6000 joules to kilocalories.
E(kcal-IT) = 6000 J / 4186.8 = 1.433 kcalIT
Convert 8000 joules to kilocalories.
E(kcal-IT) = 18000 J / 4186.8 = 1.910 kcalIT
Convert 18000 joules to kilocalories.
E(kcal-IT) = 18000 J / 4186.8 = 4.299 kcalIT
2 kcal15 = 4185.5 J
So energy in joules E(J) is equal to the energy in 15°C kilocalories E(kcal15) divided by 4185.5:
E(kcal15) = E(J) / 4185.5
Convert 6000 joules to kilocalories.
E(kcal15) = 6000 J / 4185.5 = 1.433 kcal15
Convert 8000 joules to kilocalories.
E(kcal15) = 8000 J / 4185.5 = 1.911 kcal15
Convert 18000 joules to kilocalories.
E(kcal15) = 18000 J / 4185.5 = 4.300 kcal15
1 kcal20 = 4182 J
so energy in joules E(J) is equal to the energy in 20°C kilocalories E(kcal20) divided by 4182:
E(kcal20) = E(J) / 4182
Convert 6000 joules to kilocalories.
E(kcal20) = 6000 J / 4182 = 1.434 kcal20
Convert 8000 joules to kilocalories.
E(kcal20) = 8000 J / 4182 = 1.912 kcal20
Convert 18000 joules to kilocalories.
E(kcal20) = 18000 J / 4182 = 4.304 kcal20

One calorie (kcal) equals 4.18 kJ or 4,184 joules (J) ( 1 ). To convert from calories to kJ, multiple calories by 4.18. Read more
In SI units, one kilocalorie per mole is equal to 4.184 kilojoules per mole (kJ/mol), which is approximately 6.9477×10−21 joules per molecule, or approximately 0.043 eV per molecule. At room temperature (25 °C, 77 °F, or 298.15 K) this is approximately equal to 1.688 units in the KT term of Boltzmann's equation. Read more
