lb-ft/h to mW

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 represents the amount of work done by a force of one pound acting through a distance of one foot in one hour.

• Symbol: The symbol for pound foot per hour is lbf·ft/h.

• Usage: This unit is commonly used in engineering and mechanical contexts, particularly when discussing torque and rotational power in machines and engines.

milliwatt

• Definition: A milliwatt is a unit of power equal to one thousandth of a watt. It is used to measure the rate of energy transfer, often in electrical and electronic contexts.

• Symbol: The symbol for milliwatt is mW.

• Usage: Milliwatts are frequently used in various applications, including electronics, telecommunications, and medical devices, where small amounts of power are involved.

Origin of the pound foot per hour

• The pound foot per hour originated from the Imperial system of measurement, which was developed in the early 19th century in Britain. It combines the pound, a unit of force, with the foot, a unit of length, to quantify work done over time. This unit is particularly useful in mechanical engineering and physics.

Origin of the milliwatt

• The milliwatt is derived from the watt, which was named after James Watt, a Scottish inventor and mechanical engineer who made significant improvements to the steam engine in the late 18th century. The prefix “milli-” indicates one thousandth, making the milliwatt a convenient unit for measuring low levels of power in modern electrical and electronic applications.
