Converting between foot-pounds per second (ft⋅lb/s) and kilowatts (kW) involves understanding the relationship between these units of power and applying the appropriate conversion factor.
The key is knowing the conversion factor between foot-pounds per second and watts, and then between watts and kilowatts. Since this is a conversion between units of power, the base (binary vs. decimal) does not affect the conversion.
To convert from foot-pounds per second to kilowatts, you first convert foot-pounds per second to watts, and then convert watts to kilowatts.
Convert ft⋅lb/s to Watts:
Multiply the value in foot-pounds per second by the conversion factor 1.35582.
Convert Watts to Kilowatts:
Divide the value in watts by 1000 to get kilowatts.
Combined Formula:
Combining these two steps into a single formula:
Example: Convert 1 ft⋅lb/s to kW
Therefore, 1 foot-pound per second is equal to 0.00135582 kilowatts.
To convert from kilowatts to foot-pounds per second, you reverse the process.
Convert Kilowatts to Watts:
Multiply the value in kilowatts by 1000 to get watts.
Convert Watts to ft⋅lb/s:
Divide the value in watts by 1.35582 to get foot-pounds per second.
Combined Formula:
Combining these two steps into a single formula:
Example: Convert 1 kW to ft⋅lb/s
Therefore, 1 kilowatt is equal to approximately 737.56 foot-pounds per second.
While the foot-pound per second is a more traditional unit, James Watt, a Scottish inventor and mechanical engineer, significantly contributed to the development of the steam engine and is the namesake of the watt, the SI unit of power. His work laid the foundation for understanding and measuring power, which is crucial in various engineering and scientific applications. His work with steam engines and the measurement of their power output helped standardize the concept of horsepower, which is related to foot-pounds per second.

Foot-pounds per second is a unit of power, commonly used in mechanical engineering and physics, especially in the United States. It represents the amount of work done (in foot-pounds) per unit of time (in seconds). Let's break it down.
Foot-pounds per second (ft⋅lb/s) is a unit of power that expresses the rate at which work is performed. One foot-pound is the amount of energy required to raise a one-pound object a distance of one foot against gravity. Therefore, foot-pounds per second tell you how quickly that work is being done.
Foot-pound (ft⋅lb): This is a unit of energy or work. It's calculated as the force in pounds multiplied by the distance in feet.
Second (s): This is the unit of time.
Combining these gives you:
Foot-pounds per second can be converted to other common units of power:
Watts (W): The standard SI unit of power.
Horsepower (hp): A common unit of power, especially for engines.
Therefore:
While there isn't a specific "law" tied directly to foot-pounds per second, the concept of power and its measurement is closely related to the work of James Watt. He improved the steam engine, and horsepower was originally defined to compare the power of steam engines to that of horses. While horsepower is more commonly associated with Watt, foot-pounds per second provides a more granular and fundamental way to express power.
Lifting Objects: A motor lifting a 100-pound object 5 feet in 2 seconds is doing work at a rate of:
Pumping Water: A pump lifting water 20 feet at a rate of 10 pounds per second is performing work at a rate of:
Small Electric Motors: Many small electric motors are rated in terms of horsepower or watts, but you can convert those ratings to foot-pounds per second to understand the rate at which they can perform work. For example, a motor rated at 1/4 horsepower is approximately 137.5 ft⋅lb/s.
Foot-pounds per second are valuable for calculating the rate at which machines perform work, enabling engineers to design and analyze mechanical systems. Understanding this unit provides a fundamental grasp of power and its relationship to work and time.
Let's explore the concept of kilowatts, a crucial unit for understanding power in various applications.
A kilowatt (kW) is a unit of power in the International System of Units (SI). It represents 1,000 watts. Power, in physics, is the rate at which energy is transferred, used, or transformed. One watt (W) is defined as one joule per second (1 J/s). Therefore, one kilowatt is 1,000 joules per second.
The term "kilowatt" is formed by adding the prefix "kilo-" to the unit "watt." "Kilo-" is a standard prefix in the metric system that denotes a factor of 1,000.
Thus, a kilowatt is simply 1,000 watts. This makes it easier to express larger amounts of power in a concise and manageable way.
As mentioned above Watt (W) is named after James Watt, a Scottish inventor and mechanical engineer whose improvements to the steam engine were fundamental to the changes brought by the Industrial Revolution. While the kilowatt is a derived unit (1000 watts), it's directly linked to the base unit named in his honor. Watt's work on steam engines significantly contributed to our understanding and utilization of power.
Kilowatts are commonly used to measure the power consumption of various appliances and systems:
It's essential to differentiate between kilowatts (kW) and kilowatt-hours (kWh). Kilowatts measure power (the rate of energy use), while kilowatt-hours measure energy (the total amount of energy used over time). One kWh is the amount of energy used by a 1 kW device operating for one hour. Utility companies typically bill for energy usage in kWh.
