Conversion Volt-ampere to Watt. In addition, our hot tub pumps and heater are designed to deliver maximum performance using minimum energy. When you multiply 745.7 watts by 2.5 hp, you get 1,864.25 watts. Another common but popular unit of power that motors are rated in is watts. Given a normal 120 Volt, 60 hz power source and the ampere reading from equipment, make the following calculation: POWER (WATTS) = 120 * 2.5 ANSWER: 300 WATTS. Boiler Horsepower: It is denoted by the symbol hp(S) and is approximately equivalent to 33,475 Btu/h or 9809.5 watts. A basic understanding of the brake horsepower of a motor is the key to ensure that the output is strong enough to drive both, the motor and any auxiliary components. One metric horsepower (often abbreviated PS, from the German Pferdestrke) is about 736 watts while one mechanical horsepower is about 746 watts, so 1 PS equals 0.986 hp. To Find Volt-Amperes (VA) 1. Amps = Watts / Volts. The formula for calculating power in electrical circuits is P=VI. There are many different standards and types of horsepower. In the end, you will also find a watts-to-amps table at 120V electric potential. Horsepower = Watts / 746. When sizing by KVA use the following calculation to determine watts: KW= KVA x Calculating the Horsepower of a Vehicle. So if you took a 1-horsepower horse and put it on a treadmill, it could operate a generator producing a continuous 746 watts. After the power has been converted to watts, use the Watts Law formula to find current in amps. By using a combination of average METs/Watts and total distance, your clients can accurately measure progress. The conversion from watts to horsepower is 745.7 watts = 1 hp. Learn why owning a Hot Spring spa means lower operating costs. Technical applications use watts or kilowatts as their unit of measure, but popular culture dictates that mechanical output also be calculated in terms of horsepower. Multiply the amount of horsepower by 2.544 to calculate the amount of MBH. 1 hp = 745.8 watts. When Volts and Amperes are Known. We derive the formula for amperage from that to be I=P/V. For example, the number of watts is 250,000. 1 horsepower is equivalent to 746 watts. In this context, 1 horsepower is equal to 746 watts. (Multiplying the above kilowatt answer by 1.340 converts it to horse- power [i.e., 1 kW = 1.340 horsepower]). There are several ways to calculate the horsepower of a vehicle. Watt: A For this reason, when determining the power your generator is to provide, it is important to calculate electric motor requirements at 3* times the running watts to compensate for the surge needed to start the motor. k = 0.000133 A constant to yield power in kilowatts. One horsepower is equal to 745.7 watts. At 120V, 120 watts make 1 amp. The metric horsepower has an electric equivalent of: 1 HP = 764 watts. HP is a unit for power, as it can be measured by W (watt). Another common unit of power that motors are rated in is watts. After the steps above the final formula for converting horsepower to amps is: Amps = To demonstrate how watts can be converted to amps, we solved a few examples of how many amps is 500 watts, 1000 watts, and 3000 watts. The unit of electric power - 1 watt - is equal to the power produced by an electrical current of 1 amp at a potential difference of 1 volt. Volt-amperes are useful only in the context of alternating current (AC) circuits. Measuring by distance or steps does not provide a complete profile. Convert to Amps. The rotor swept area, A, is important because the rotor is the part of the turbine that captures the wind energy. Watts = Watts . Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts and the metric horsepower, which is approximately 735.5 watts. For example, 300 metric horsepower would be about 296 mechanical horsepower while 150 PS is about 148 hp. Rakesh on May 19, 2017: Hi Eugene, I have a lot of electrical work to do on daily basis. First we need to convert the horsepower to watts. Multiplying that amount by 0.293 results in 73,250 MBH. (325) 515-4046 Power is in general rated in watt (W) or horsepower (hp).The old imperial unit horsepower is equal to 746 watts (0.745 kW) or 33000 lb ft per minute (or 550 lb ft per second).. So, the larger the rotor, the more energy it can capture. Like any device that does work (transfers energy across a distance), its effectiveness is measured in power. 517 nozzle for 12" to 16" fan width But Im a non technical person. Amps = Watts Volts. 1000-3000 PSI piston pump for high pressure and better coverage Easy twist knob pressure control Stainless steel paint pick-up is easy to clean, won't rust or corrode Lightweight, durable spray gun with built in filter and trigger-lock for easy flushing and cleaning No. That means that 1 amp = 120 watts. I=1492/240 (for single phase), which means I=6.21A. The metric horsepower also equals 32,549 foot-pounds per minute or 0.9863 - this is what some European and German manufacturers use when they provide engine power. 1 watt = 1 / 746 hp; 1 hp = 746 watts = 0.76 kW The term was coined by engineer James Watt (also namesake of the unit watts). Although watts and kilowatts are more common units of power measurement, horsepower is still commonly used for high-output electrical devices in the United States. POWER (WATTS) = VOLTS x AMPERES. Heres a quick useful piece of info: How many watts make an amp? To find this, divide the horsepower by the efficiency in decimal form. The rate of doing work is equal to the rate of using energy since the a force transfers one unit of energy when it does one unit of work. To Find Watts. This calculation is only for cases where the force is in the direction of the velocity, and there are many cases where that is not so. The watts equation for an electrical circuit takes into account the voltage across the circuit V , measured in volts, and the current I , measured in amps, passing through it.In mechanics, the definition of power is the rate of doing work W .It's defined as W / t , where t is the time it takes for the work to be completed. So, if the motor is 2HP, 2HP=1492 watts. See All Farm Equipment For Sale near you By Watts Tractor Co. 2112 US Highway 277 N, Anson, Texas 79501. The conversion from watts to horsepower is: 745.7 watts = 1 horsepower Horsepower is a standard measurement, whether youre talking about a car or a shop vac, and the term is so commonplace that its easy to forget it has pre-vehicular origins. Same as above. Though horsepower units are a derivative of the 33,000 ft-lbf/min, it is not critical to understanding how to calculate motor horsepower for speed and torque. If you have any more questions, just let me know! Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. 1HP=746 watts. For example, if the amount of horsepower is 10,000, then multiplying it by 2.544 will result in 25,440 MBH. 1 horsepower (over the course of an hour) is equivalent to 2,545 BTU (British thermal units). A horsepower is equal to 550 ft lb/s, and a kilowatt is 1000 watts. A volt-ampere (VA) is the unit used for the apparent power in an electrical circuit. If these 10, 100 watt light bulbs run for one hour, they will consume 1,000 watthours or 1 KWH for the month (10 x 100 = 1000 watts / 1000 = 1 KW x 1 hour = 1 KWH). Volts = Watts / Amps. Watts, METs and Calories METs/Watts provide a more accurate way to show progress because they take into account the intensity it takes to complete an activity. These estimates calculate that for a 1 or 2-bedroom house, average gas consumption currently stands at around 8,000kWh, with electricity consumption approximately 2,000kW. We have a appliance with a nameplate shows 2.5 amps. These figures rise to 12,500 kWh of gas and 3,100kWh of electricity for a typical 3 or 4-bedroom house. Pumps straight from 1 or 5 gallon buckets for easier cleanup. 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. 1. Math Conversions.
