lb-ft/h to W

pound foot per hour

• Definition: Pound foot per hour (lb-ft/h) is a unit of power that measures the rate at which work is done or energy is transferred. It specifically quantifies the rotational power, where one pound foot is the torque applied over one hour.

• Symbol: The symbol for pound foot per hour is lb-ft/h.

• Usage: This unit is commonly used in engineering contexts, particularly in mechanical and automotive engineering, where it helps to describe the power output of engines and motors.

watt

• Definition: A watt (W) is the SI unit of power, defined as one joule per second. It is a measure of the rate of energy transfer or conversion.

• Symbol: The symbol for watt is W.

• Usage: Watts are widely used to quantify electrical power, light output, and heat production in various applications, from household appliances to industrial machinery.

Origin of the pound foot per hour

• The pound foot per hour has its roots in the imperial system of measurements, which is derived from the British system. It combines the concept of torque (pound foot) with a time dimension (hour) to express power in a rotational context.

Origin of the watt

• The watt is named after James Watt, an 18th-century Scottish inventor and mechanical engineer who played a significant role in the development of the steam engine. The unit was adopted in the late 19th century as a standard measure of power in various scientific and engineering fields.
