Convert horsepower (electric) to petajoule/second
Please provide values below to convert horsepower (electric) [hp (electric)] to petajoule/second [PJ/s], or Convert petajoule/second to horsepower (electric).
How to Convert Horsepower (Electric) to Petajoule/second
1 hp (electric) = 7.46e-13 PJ/s
Example: convert 15 hp (electric) to PJ/s:
15 hp (electric) = 15 × 7.46e-13 PJ/s = 1.119e-11 PJ/s

Horsepower (Electric)
Electric horsepower (hp) is a unit of power used to measure the rate at which electrical energy is converted into mechanical energy or work, equivalent to approximately 746 watts.
History/Origin
The electric horsepower was developed as an adaptation of the mechanical horsepower to quantify electrical power output, especially in electric motors and generators. It became a standard unit in electrical engineering to express the power of electric motors and appliances.
Current Use
Electric horsepower is used primarily in specifying the power of electric motors, generators, and other electrical devices, particularly in industries where electrical power measurement is essential for performance and efficiency assessments.
Petajoule/second
A petajoule per second (PJ/s) is a unit of power representing the transfer or conversion of one petajoule of energy every second.
History/Origin
The petajoule (PJ) is a metric unit of energy introduced as part of the International System of Units (SI) to measure large quantities of energy. The concept of power in terms of energy per unit time has been fundamental in physics, with the watt (W) as the SI base unit. The petajoule per second emerged as a large-scale unit for high-energy power measurements, especially in fields like energy production and scientific research.
Current Use
Petajoule per second is used in scientific and engineering contexts to quantify extremely high power levels, such as in nuclear energy, large-scale power generation, and astrophysics. It is also used in theoretical and large-scale energy calculations where conventional units like watts are insufficient.
