Attojoule

The attojoule (aJ) is a unit of energy in the International System of Units (SI). It is equal to one quintillionth of a joule (0.000000000000000001 J). The attojoule is commonly used to measure extremely small amounts of energy, such as the energy content of individual photons.

Origin:

The attojoule is derived from the joule, which is named after James Prescott Joule, an English physicist. The prefix 'atto-' signifies a factor of one quintillionth, making the attojoule equal to one quintillionth of a joule.

Horsepower hour

The horsepower hour (hp*h) is a unit of energy commonly used to measure the energy output of engines. It is equal to the energy expended by a one horsepower engine operating for one hour.

Origin:

The horsepower hour is derived from the horsepower, which is a unit of power named after James Watt, a Scottish engineer and inventor. The horsepower hour measures the amount of energy used over time.
