Convert horsepower to erg/second
Please provide values below to convert horsepower [hp] to erg/second [erg/s], or Convert erg/second to horsepower.
1 hp = 7457000000 erg/s. To convert horsepower to erg/second, multiply the value by 7457000000; to go the other way, divide by it (1 erg/s = 1.3410e-10 hp). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 hp = 7457000000 erg/s
- 1 erg/s = 1.3410e-10 hp
- 10 hp = 74570000000 erg/s
- 100 hp = 745700000000 erg/s
How to Convert Horsepower to Erg/second
1 hp = 7457000000 erg/s
Example: convert 15 hp to erg/s:
15 hp = 15 × 7457000000 erg/s = 111855000000 erg/s

Horsepower
Horsepower (hp) is a unit of power measurement originally developed to compare the power of engines and motors, representing the rate at which work is done or energy is transferred.
History/Origin
The term was introduced in the late 18th century by James Watt to compare the power of steam engines to draft horses. It became a standard unit in engineering and automotive industries, with its definition evolving over time from mechanical to metric standards.
Current Use
Horsepower is widely used today to rate the power output of engines, motors, and other machinery, especially in automotive, aerospace, and industrial applications. It remains a common unit for expressing engine power in many countries.
Erg/second
The erg/second (erg/s) is a unit of power representing the rate of energy transfer or conversion, where one erg per second equals the transfer of one erg of energy per second.
History/Origin
The erg is an older CGS (centimeter-gram-second) unit of energy, introduced in the early 20th century for scientific calculations. The erg/second was used in physics to quantify power in contexts where the CGS system was prevalent, especially in astrophysics and theoretical physics.
Current Use
Today, the erg/second is rarely used outside specialized scientific fields; the SI unit watt (W) is preferred for measuring power. However, erg/s may still be encountered in historical data, astrophysics, or when working with CGS-based calculations.
