## What does horsepower mean in terms of energy?

Horsepower is a unit of power. Power describes how fast energy is exchanged; a use of energy divided by how long it takes to use that energy.

## What is the relationship between horsepower and torque?

The relationship between engine power and torque may be expressed as horsepower (hp) = [torque (lb-ft) × revolutions per minute (RPM)] ÷ 5252 In simple terms, torque describes how much work an engine can do and horsepower describes how quickly that work can be done.

## How is the horsepower of an engine measured?

Horsepower is a unit of power. Power describes how fast energy is exchanged; a use of energy divided by how long it takes to use that energy. Therefore the measurement of horsepower refers to what the sustained output of an engine is.

## What does horsepower in a supercar mean?
