1 horsepower hour = 2.68452 × 10²⁴ attojoule.
1 attojoule = 3.725061 × 10⁻²⁵ horsepower hour.
Multiply the value in horsepower hour by 2.68452 × 10²⁴ to get the result in attojoule. Example: 5 hph × 2.68452 × 10²⁴ = 1.34226 × 10²⁵ aJ.
Horsepower hour (hph) is a unit of energy.
1 horsepower hour = 2,684,520 joule (J)
1 horsepower hour = 641,186.5 calorie [I.T.] (cal)
1 joule = 3.725061 × 10⁻⁷ horsepower hour
Use the converter above to convert horsepower hour 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.
