1 attojoule = 2.388459 × 10⁻²² kilocalorie [I.T.].
1 kilocalorie [I.T.] = 4.1868 × 10²¹ attojoule.
Multiply the value in attojoule by 2.388459 × 10⁻²² to get the result in kilocalorie [I.T.]. Example: 5 aJ × 2.388459 × 10⁻²² = 1.194229 × 10⁻²¹ kcal.
Attojoule (aJ) is a unit of energy.
1 attojoule = 1 × 10⁻¹⁸ joule (J)
1 attojoule = 2.388459 × 10⁻¹⁹ calorie [I.T.] (cal)
1 joule = 1 × 10¹⁸ attojoule
The SI prefix atto- stands for 10⁻¹⁸, so 1 attojoule = 10⁻¹⁸ joule.
Use the converter above to convert attojoule into any other unit of energy.
Kilocalorie [I.T.] (kcal) is a unit of energy. "I.T." stands for the International Table definition.
1 kilocalorie [I.T.] = 4,186.8 joule (J)
1 kilocalorie [I.T.] = 1,000 calorie [I.T.] (cal)
1 joule = 0.0002388459 kilocalorie [I.T.]
The SI prefix kilo- stands for 1,000, so 1 kilocalorie [I.T.] = 1,000 calorie [I.T.].
