Web27 de abr. de 2024 · For air conditioning equipment and heat pumps, its BTU/h rating is how much heat it moves per hour. An air conditioner captures heat indoors and moves it outdoors. A heat pump absorbs heat from outdoors and moves it inside. Direct Equivalent BTU to kW Calculator (Heating) The first BTU to kW calculator gives you the direct … WebThe SI unit for heat capacity of an object is joule per kelvin (J/K or J⋅K −1 ). Since an increment of temperature of one degree Celsius is the same as an increment of one kelvin, that is the same unit as J/°C. The heat capacity of an object is an amount of energy divided by a temperature change, which has the dimension L 2 ⋅M⋅T −2 ⋅Θ −1.
