What is the common unit used to measure power?

• A. Foot-pounds
• B. Newton-meters
• C. Horsepower
• D. Watts

Answer: (C)

The common unit used to measure power, particularly in various engineering contexts, is Watts. Power is defined as the rate at which work is done or energy is transferred over time. One Watt is equivalent to one joule per second, indicating how much work can be accomplished in a given timeframe. While horsepower is also a recognized unit of power, particularly in automotive and mechanical engineering to express the power output of engines, the metric system and the International System of Units (SI) primarily utilize Watts as the standard unit for power. This makes Watts the most universally applicable measurement. Foot-pounds and Newton-meters are both units that measure torque or work done rather than power, which distinguishes them from the concept of power itself. Therefore, Watts is the most common unit utilized in measuring power across various fields of study.
