lb-ft/h to J/s

pound foot per hour

• Definition: Pound foot per hour is a unit of power that measures the rate at which work is done or energy is transferred. It signifies the amount of energy in pound-feet applied over the duration of one hour.

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

• Usage: This unit is often used in engineering and mechanical contexts to express the power output of engines and motors, especially in the United States where customary units are prevalent.

joule per second

• Definition: Joule per second, commonly known as a watt, is the SI unit of power. It represents the rate at which energy is transferred or converted, with one joule per second equivalent to one watt.

• Symbol: The symbol for joule per second is J/s or W.

• Usage: Joules per second are widely used in physics and engineering to quantify electrical power, mechanical work, and thermal energy transfer, making it a critical unit in various scientific fields.

Origin of the pound foot per hour

• The pound foot per hour unit originates from the Imperial system of measurements, which was historically used in the British Empire. It combines the pound, a unit of force or weight, and the foot, a unit of length, to describe energy transfer over time. This unit has been utilized in various industries, particularly in the United States, where customary units remain in use.

Origin of the joule per second

• The joule per second is derived from the work of James Prescott Joule, a 19th-century physicist who studied the nature of heat and energy. The joule itself is defined as the energy transferred when a force of one newton is applied over a distance of one meter. The joule per second reflects the modern International System of Units (SI) and is widely accepted and used globally in scientific and engineering contexts.
