1 kilocalorie [15° C] = 4.1858 × 10²¹ attojoule.
1 attojoule = 2.38903 × 10⁻²² kilocalorie [15° C].
Multiply the value in kilocalorie [15° C] by 4.1858 × 10²¹ to get the result in attojoule. Example: 5 kcal × 4.1858 × 10²¹ = 2.0929 × 10²² aJ.
Kilocalorie [15° C] (kcal) is a unit of energy. This value is defined using water at 15 °C.
1 kilocalorie [15° C] = 4,185.8 joule (J)
1 kilocalorie [15° C] = 999.7612 calorie [I.T.] (cal)
1 joule = 0.000238903 kilocalorie [15° C]
The SI prefix kilo- stands for 1,000, so 1 kilocalorie [15° C] = 1,000 calorie [I.T.].
Use the converter above to convert kilocalorie [15° C] 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.
