1 kilojoule = 1 × 10²¹ attojoule.
1 attojoule = 1 × 10⁻²¹ kilojoule.
Multiply the value in kilojoule by 1 × 10²¹ to get the result in attojoule. Example: 5 kJ × 1 × 10²¹ = 5 × 10²¹ aJ.
Kilojoule (kJ) is a unit of energy.
1 kilojoule = 1,000 joule (J)
1 kilojoule = 238.8459 calorie [I.T.] (cal)
1 joule = 0.001 kilojoule
The SI prefix kilo- stands for 1,000, so 1 kilojoule = 1,000 joule.
Use the converter above to convert kilojoule 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.
