Terms and Units Prior to beginning a discussion on heat transfer in thermal interface gap filler materials, a number of terms and units require definition. What is a watt per meter kelvin? significant figures. The inside of the sphere is at a temperature of 415 K, and the outside of the sphere is at a temperature of 275 K. (a) What is the rate of heat conduction through the sphere, in units of Watts? Watt/Meter-K : The watt per meter per kelvin is a derived SI unit of thermal conductivity. Thermal Diffusivity: Describes the ability of a material to lose heat by conduction - depends on conductivity, density, and heat capacity by k = k/rC p. Note - has units of length 2 /time - if a temperature change occurs with a time interval t then the changes will occur a distance on the order of Ökt. These two units (Thermal conductivity and R-Value) can be converted to each-other very easily doing Say if x is our Thermal conductivity value for our material, hence R-Value will be, a is the thickness in Meters $$ \frac{1}{x}* (a) $$ share | cite | improve this answer | follow | answered Oct 4 '13 at 0:50. Thermal conductivity is a result of phonon propagation through the crystal lattice. However they provide an option to return results either in CGS or SI unit. Watt/Centimeter-°C : The watt per centimeter per degree Celsius is a decimal unit of thermal conductivity. A low value indicates a good insulator; a high value indicates a good conductor. Since one DTU per second is a watt, this can also be written as watts per meter per degree Celsius ( (W/m) / °C ). Calorimeter. Normally in imperial units thermal conductivity is given in Btu/in/hr/ft^2/degF. select units . Also, what does a materials' thermal conductivity tell me? Its symbol are W/m•K and W•m⁻¹•K⁻¹. The thermal conduction equation is calculated using the following formula: represents the heat energy transferred per unit time through the material. BTU stands for British Thermal Units, h or hr for "hour," ft for foot, and °F for degree Fahrenheit. . Pure copper's in imperial units is 223 BTU/h/ft °F.
