Therefore the horsepower of the engine of the vehicle will be 9.52 HP. Amount: 1 Hydraulic horsepower (hp) of power. The conversion from watts to horsepower is:Īlso, One Horsepower equals to 33,000 lb.
#Horsepower to watts how to#
Though horsepower units is a derivative of the 33,000 ft-lbf / min, it is not critical to understanding how to calculate motor horsepower for speed and torque.Īnother common but popular unit of power that motors are rated in is watts. Get the huge list of Physics Formulas here The derivation of these constants is as follows: To measure the horsepower of an engine or motor, you need to determine the torque. If the units are different then first we have to make the unit conversion. How to Convert Horsepower (metric) to Watt 1 horsepower (metric) 735.49875 W 1 W 0.0013596216 horsepower (metric) Example: convert 15 horsepower (metric) to W: 15 horsepower (metric) 15 × 735.49875 W 11032. In metric units, one horsepower is equivalent to approximately 745.7 watts. 5252 is another common constant if the speed is in rpm and torque is in ft-lbf. Here, 63025 is a constant when using rpm for speed and in-lbf for torque units. For example, if we have a motor with 3,000 rpm and 6 in-lbf then the horsepower can be calculated below.
But later on, its usage was expanded to different types of piston engines, electric motors, turbines, and other machinery.įirst, we will see some equations to help in calculating the horsepower:įor the electric motors, we can calculate the power or horsepower from the torque and speed. Note that the driving force of an electric motor is torque - not horsepower. 1 hp (I) 745.699872 W, where one mechanic or hydraulic horsepower is equivalent to 745.699872 Watts. In earlier days it was used to measure steam engine power output compared to the power of draft horses. Power is quantified in watts (J/s) or horse power. Horsepower (hp) is a unit in the English system used to express the rate at which mechanical energy is expended. It is a unit of power that compares the power of a machine to the muscle power of the horse. This term of Horsepower was invented by James Watt. It is defined as the work done by a person or machine per unit amount of time. Horsepower is a popular imperial unit of power of an engine. work with power's values and properties.2 Solved Examples on Horsepower Formula Horsepower Formula What is horsepower? The total horsepower developed by water falling from a given height is the product of the mass flow rate in pounds per minute times the falling height in feet divided by 33000 and can be expressed as: P hp m min h a g / 33000 (1) where. for conversion factors between unit pairs.ģ. In the SI system the unit of power is watt (W, Nm/s, J/s). in practicing Hydraulic horsepower and watts ( hp 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: Hydraulic horsepower (hp) is used for measuring power.Ībbreviation, or prefix, for Hydraulic horsepower is: Conversion tool with multiple power units. Prove that 1 horsepower 746 watts using concepts of current electricity. 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. Prove that 1 horsepower 746 watts using concepts of current electricity. hp/W power conversion resultĬonversion chart - Hydraulic horsepower to wattsġ Hydraulic horsepower to watts = 745.70 WĢ Hydraulic horsepower to watts = 1,491.40 Wģ Hydraulic horsepower to watts = 2,237.10 WĤ Hydraulic horsepower to watts = 2,982.80 Wĥ Hydraulic horsepower to watts = 3,728.50 WĦ Hydraulic horsepower to watts = 4,474.20 Wħ Hydraulic horsepower to watts = 5,219.90 WĨ Hydraulic horsepower to watts = 5,965.60 Wĩ Hydraulic horsepower to watts = 6,711.30 Wġ0 Hydraulic horsepower to watts = 7,457.00 Wġ1 Hydraulic horsepower to watts = 8,202.70 Wġ2 Hydraulic horsepower to watts = 8,948.40 Wġ3 Hydraulic horsepower to watts = 9,694.10 Wġ4 Hydraulic horsepower to watts = 10,439.80 Wġ5 Hydraulic horsepower to watts = 11,185.50 WĬonvert power of Hydraulic horsepower (hp) and watts (W) units in reverse from watts into Hydraulic horsepower.
