It measures the strength of different muscle groups. An isokinetic dynamometer consists of an exercise machine with sensors, connected to a computer. Some athletes use special devices for these calculations, record their performance with respect to power output, and then analyze it to determine the effectiveness of their workout program.Ī chassis dynamometer can measure torque and power delivered by the power train of a vehicleĭynamometers can also be used to calculate the strength of people for sports or medical reasons. For example, this calculator shows that a person 170 cm tall and weighing 70 kg will produce a power output of 39.5 watts by doing 50 push-ups for 10 minutes. Some websites help athletes calculate the work performed and the power output for different types of physical exercises, based on the weight of the athlete and of the equipment used, the distance traveled, estimated using the athlete’s height for exercises like weight lifting, and the exercise duration. ![]() For example, the power of an athlete throwing a basketball can be calculated by finding the force, with which she propels the ball for a given distance and the time during which she completes this work. Work produced by animals and humans can be measured using power. Machines are not the only objects that can be evaluated through power. Residential split system air conditioners: 20–40 kilowatts.Even though watts as a unit have existed nearly as long as horsepower, the latter is more commonly used in the automobile industry.ĥ050 LED strip. It is now believed that horses are not capable of working at this capacity for a long period of time, but the unit stays unchanged. ![]() One horsepower is equivalent to 746 watts. Watt measured this unit of power by observing and evaluating the work of draft horses in a mill. This measure was later used for other machines such as automobiles. Thus, having a standardized measure was useful for comparing the power output between different engines and horses. Until the invention of engines, humans relied mainly on human and animal manual labor, so it was natural for Watt to compare the power output of the new steam engine with the power of horses, especially because not every mine where he marketed his steam engine used technology some used only horses. To show the efficiency of the improved engine Watt suggested horsepower as a unit of power. Power is one indicator of efficiency - if a given engine is modified and its power output increases, so does its efficiency. After the steam engine was invented, James Watt, an inventor and engineer, worked on improving it and on making it more efficient. Until the invention of engines, power was not measured formally, and there were no units associated with it. Along with watts, horsepower as a unit is also used. Power is measured in joules per second, or watts. work with power's values and properties.2 hp or 1.5 kW horse-drawn wagon with 20 passengers Units for conversion factors between unit pairs.ģ. in practicing foot pounds per second and watts ( ft lbf/s vs. With the above mentioned two-units calculating service it provides, this power converter proved to be useful also as a teaching tool:ġ. W Other applications for this power calculator. Converter type: power unitsįirst unit: foot-pound-force per second (ft lbf/s) is used for measuring power.Ībbreviation, or prefix, for foot-pound-force per second is: Conversion tool with multiple power units. Power units represent power physics, which is the rate at which energy is used-up, either transformed or transferred from its source to elsewhere, by various ways within the nature of physics. ![]() ft lbf/s/W power conversion resultĬonversion chart - foot pounds per second to wattsġ foot-pound-force per second to watts = 1.36 WĢ foot pounds per second to watts = 2.71 Wģ foot pounds per second to watts = 4.07 WĤ foot pounds per second to watts = 5.42 Wĥ foot pounds per second to watts = 6.78 WĦ foot pounds per second to watts = 8.13 Wħ foot pounds per second to watts = 9.49 WĨ foot pounds per second to watts = 10.85 Wĩ foot pounds per second to watts = 12.20 Wġ0 foot pounds per second to watts = 13.56 Wġ1 foot pounds per second to watts = 14.91 Wġ2 foot pounds per second to watts = 16.27 Wġ3 foot pounds per second to watts = 17.63 Wġ4 foot pounds per second to watts = 18.98 Wġ5 foot pounds per second to watts = 20.34 WĬonvert power of foot-pound-force per second (ft lbf/s) and watts (W) units in reverse from watts into foot pounds per second. ![]() It is the EQUAL power value of 1 foot-pound-force per second but in the watts power unit alternative.
