To convert foot-pounds per second (ft·lbf/s) to British thermal units per second (BTU/s), you need to understand the relationship between the two units.
1 BTU is equivalent to 778.169 foot-pounds. Therefore, to convert foot-pounds per second to BTU per second, you use the following conversion factor:
1 \text{ BTU/s} = 778.169 \text{ ft·lbf/s}
To convert 1 foot-pound per second to BTU per second:
1 \text{ ft·lbf/s} \times \left(\frac{1 \text{ BTU}}{778.169 \text{ ft·lbf}}\right) = \frac{1}{778.169} \text{ BTU/s} \approx 0.001285 \text{ BTU/s}
So, 1 foot-pound per second is approximately 0.001285 BTU per second.
10 ft·lbf/s to BTU/s 10 \text{ ft·lbf/s} \times \left(\frac{1 \text{ BTU}}{778.169 \text{ ft·lbf}}\right) = \frac{10}{778.169} \text{ BTU/s} \approx 0.01285 \text{ BTU/s}
100 ft·lbf/s to BTU/s 100 \text{ ft·lbf/s} \times \left(\frac{1 \text{ BTU}}{778.169 \text{ ft·lbf}}\right) = \frac{100}{778.169} \text{ BTU/s} \approx 0.1285 \text{ BTU/s}
500 ft·lbf/s to BTU/s 500 \text{ ft·lbf/s} \times \left(\frac{1 \text{ BTU}}{778.169 \text{ ft·lbf}}\right) = \frac{500}{778.169} \text{ BTU/s} \approx 0.6425 \text{ BTU/s}
Car Engine Power: An average car engine might produce around 200 ft·lbf/s of power. Converting this to BTU/s: 200 \text{ ft·lbf/s} \times \left(\frac{1 \text{ BTU}}{778.169 \text{ ft·lbf}}\right) \approx 0.257 \text{ BTU/s}
Human Power Output: A healthy adult might be able to sustain an output of about 100 ft·lbf/s for some time (e.g., cycling). Converting this to BTU/s: 100 \text{ ft·lbf/s} \times \left(\frac{1 \text{ BTU}}{778.169 \text{ ft·lbf}}\right) \approx 0.1285 \text{ BTU/s}
Electric Motor: A small electric motor might work at about 1,000 ft·lbf/s. Converting this power: 1,000 \text{ ft·lbf/s} \times \left(\frac{1 \text{ BTU}}{778.169 \text{ ft·lbf}}\right) \approx 1.285 \text{ BTU/s}
Using these examples, you can see how foot-pounds per second convert to BTU per second in practical, real-world situations.

Foot-pounds per second (ft-lbf/s) is a unit of measurement that represents the rate at which work is being done, typically in applications involving mechanical power or energy transfer.
In essence, it's a measure of how fast an object can apply force to a surface over time. To break it down:
So, if something is doing 100 ft-lbf/s of work, it means that it's capable of delivering 100 foot-pounds of work in just one second. This can be useful for measuring the power output of engines, motors, or other machines that convert energy into motion or mechanical work.
British Thermal Units (BTUs) are a unit of energy, and when measured over time, they can be expressed in various ways to indicate different rates of energy transfer. British thermal units per second (or BTU/s, also denoted as Btu/s) is a measure of the rate at which heat or energy is being transferred.
It's essentially an expression of how quickly one BTU unit of energy is being used up or transferred over a one-second period. This unit is commonly used in discussions about power and rates of energy consumption or production, particularly when dealing with processes that involve significant amounts of energy, such as industrial operations, heating systems, and even some types of engines.
To put this into perspective, consider that 1 watt (a standard unit of electrical power) is equivalent to 3.412 BTU/s. Thus, a device or process consuming 100 watts would be using approximately 341.2 BTUs per second.
