1 kilocalorie [I.T.] = 4.1868 × 10²¹ attojoule.
1 attojoule = 2.388459 × 10⁻²² kilocalorie [I.T.].
Multiply the value in kilocalorie [I.T.] by 4.1868 × 10²¹ to get the result in attojoule. Example: 5 kcal × 4.1868 × 10²¹ = 2.0934 × 10²² aJ.
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.].
Use the converter above to convert kilocalorie [I.T.] into any other unit of energy.
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.
