Convert attowatt to horsepower
Please provide values below to convert attowatt [aW] to horsepower [hp], or Convert horsepower to attowatt.
1 aW = 1.3410e-21 hp. To convert attowatt to horsepower, multiply the value by 1.3410e-21; to go the other way, divide by it (1 hp = 7.4570e+20 aW). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 aW = 1.3410e-21 hp
- 1 hp = 7.4570e+20 aW
- 10 aW = 1.3410e-20 hp
- 100 aW = 1.3410e-19 hp
How to Convert Attowatt to Horsepower
1 aW = 1.3410218586563e-21 hp
Example: convert 15 aW to hp:
15 aW = 15 × 1.3410218586563e-21 hp = 2.01153278798444e-20 hp

Attowatt
An attowatt (aW) is a unit of power equal to 10^-18 watts, representing an extremely small amount of power.
History/Origin
The attowatt is part of the SI prefix system introduced to denote very small quantities, with 'atto-' representing 10^-18. It has been used mainly in scientific contexts to measure minuscule power levels.
Current Use
The attowatt is rarely used in practical applications but may be referenced in scientific research involving extremely low power measurements, such as in quantum physics or nanotechnology.
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.
