heat = Overall Heat Transfer Coefficient*Area*(Outside Temperature-Inside Temperature)
Q = U*A*(to-ti)
This formula uses 4 Variables
Variables Used
Overall Heat Transfer Coefficient - The overall heat transfer coefficient, U is a measure of the overall ability of a series of conductive and convective barriers to transfer heat. (Measured in Watt per Meter² per K)
Area - The area is the amount of two-dimensional space taken up by an object. (Measured in Square Meter)
Outside Temperature - Outside Temperature is the temperature of air present outside. (Measured in Fahrenheit)
Inside Temperature - Inside Temperature is the temperature of air present inside. (Measured in Fahrenheit)
STEP 1: Convert Input(s) to Base Unit
Overall Heat Transfer Coefficient: 10 Watt per Meter² per K --> 10 Watt per Meter² per K No Conversion Required
Area: 50 Square Meter --> 50 Square Meter No Conversion Required
