What does one electron-volt represent?

One electron-volt is the energy an electron gains when it moves through an electric potential difference of one volt, commonly used in atomic and particle physics.

What is a metric horsepower hour?

A metric horsepower hour is the energy delivered by sustaining one metric horsepower for one hour, often used to express engine work over time.

Why are the converted values from eV to horsepower hours so small?

Because electron-volts measure extremely small amounts of energy compared to the much larger scale of horsepower hours, the conversion results in very small values typically shown in scientific notation.
