-
Erg is a very small energy unit, making values very large and potentially unwieldy
-
Large numerical results may increase the chance of errors without proper computational support
Frequently Asked Questions
-
What is a horsepower hour?
-
A horsepower hour (hp*h) is a unit of energy representing one horsepower delivered continuously over one hour, based mostly on the mechanical horsepower definition.
-
Why convert horsepower hour to erg?
-
Converting hp*h to erg helps bridge mechanical energy measures common in engineering with CGS energy units used in physics, astrophysics, and laboratory settings.
-
Are there variations in horsepower hour energy values?
-
Yes, the horsepower hour's energy equivalence can differ subtly depending on whether it’s mechanical horsepower or other types like metric horsepower.
Key Terminology
-
Horsepower hour (hp*h)
-
A mechanical energy unit defined as one horsepower of power applied continuously for an hour, commonly used in engineering.
-
Erg
-
The CGS unit of energy equal to 1×10⁻⁷ joule, frequently used in physics and astrophysics applications.
-
Mechanical horsepower
-
An imperial unit of power approximately equal to 745.7 watts, used as a basis for the horsepower hour energy unit.
