1 kcalth = 4.184 kJ
The energy in kilojoules E(kJ) is equal to 4.184 times the energy in thermochecmical / food kilocalories E(kcal):
E(kJ) = 4.184 × E(kcal-th)
Convert 0.3 kcalth to kilojoules.
E(kJ) = 4.184 × 0.3 kcalth = 1.2552 kJ
1 kcalIT = 4.1868 kJ
The energy in kilojoules E(kJ) is equal to 4.1868 times the energy in international kilocalories E(kcal-IT):
E(kJ) = 4.1868 × E(kcal-IT)
Convert 0.3 kcalIT to kilojoules.
E(kJ) = 4.1868 × 0.3kcalIT = 1.25604 kJ
1 kcal15 = 4.1855 kJ
The energy in kilojoules E(kJ) is equal to 4.1855 times the energy in 15°C kilocalories E(kcal15):
E(kJ) = 4.1855 × E(kcal15)
Convert 0.3 kcal15 to kilojoules.
E(kJ) = 4.1855 × 0.3kcal15 = 1.25565 kJ
1 cal20 = 4.182 kJ
The energy in kilojoules E(kJ) is equal to 4.182 times the energy in 20°C kilocalories E(kcal20):
E(kJ) = 4.182 × E(kcal20)
Convert 0.3 kcal20 to kilojoules.
E(kJ) = 4.182 × 0.3kcal20 = 1.2546 kJ
