View all measurement unit conversion calculators on the same page (may not work with all browsers requires Iframe). To use this watts to heat calculator, follow these steps: Input the temperature change. The calculators require that your browser has java script enabled. Values lower than 0.001 will be displayed in the e-format e.g. Just simply enter value 1 in Fahrenheit/Watt and see the result in. Feel free to use our online unit conversion calculator to convert the unit from Fahrenheit/Watt to Celsius/Watt. Values of 10 000 or greater will be displayed in the e-format e.g. The answer is one Fahrenheit/Watt is equal to 0.55555555555556 Celsius/Watt and that means we can also write it as 1 Fahrenheit/Watt 0.55555555555556 Celsius/Watt. Values are given to seven significant figures ( the odd result may show 9's or 0's over running). ![]() All results shown will be equivalent values. To use the measurement conversion calculators simply enter a number value into the desired field and click calculate. Also note that the therm is 100 000 Btu so its exact size depends on which Btu is being used.ĬONVERSION CALCULATORS Convert between Different Units of Measurement Index of Unit Converters The British thermal unit (Btu) can also take different values and they are named in a similar way to the calorie. Unless a clear statement is made saying otherwise, assume the IT calorie is being used.Īs a further complication, in working with food and expressing nutritional values, the unit of a Calorie (capital C) is often used to represent 1000 calories, and again it is necessary to specify which calorie is being used for that. thermochemical calorie = cal(th) = 4.184 J.International Table calorie = cal(IT) = 4.1868 J.The calorie can take 5 different values and, while these do not vary by very much, for accurate work it is necessary to specify which calorie is being used. There can be some confusion in some of the units of energy. N m = kg m 2 s -2 = CV = V A s = W s = J (Joule). Energy can exist the following forms: radiation kinetic energy potential energy chemical energy atomic energy electromagnetic energy electrical energy and heat energy. ![]() Sorry, your browser does not support JavaScript, which is needed to run this calculator Energy Definition: P (BTU/hr) = 3.412141633 ⋅ 4500W = 15,354.Energy Unit Conversion Calculator ENERGY UNITĬONVERSION CALCULATOR (Work, Heat, Energy) joule How to convert watts to BTU/hrįor Example – Convert 4500W to BTUs per hourĪns. In some regions, particularly in the United States, BTUs are also used to measure the energy content of fuels, such as natural gas and propane. ![]() Converting watt to BTUs per hour value in the power units scale. It is often used in the context of heating, ventilation, and air conditioning (HVAC) systems to quantify the amount of heat produced or removed. Equals: 3.41 BTUs per hour (Btu/h) in power. Also, explore many other unit converters or learn more about energy unit conversions. Free online energy converter - converts between 55 units of energy, including joule J, kilojoule kJ, kilowatt-hour kWh, watt-hour Wh, etc. One BTU is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit at a constant pressure. 1 Rydberg constant 2.1798741E-18 joule J Rydberg constant to joule, joule to Rydberg constant. BTU (British Thermal Unit)īTU is a unit of heat energy. Watts are commonly used to express the power consumption of electrical devices, such as light bulbs, appliances, and electronics. One watt is equal to one joule of energy per second. ![]() It measures the rate at which energy is transferred or work is done. Watt is the standard unit of power in the International System of Units (SI).
