The formula for calculating thermal conductivity is heat multiplied by the distance divided by the product of surface area times the temperature gradient. NDT Resource Center explains that thermal conductivity is the property of a material to conduct heat. Increased thermal conductivity means a high

Copper is a good conductor of heat because it contains a lattice of vibrating ions that allow electrons to move freely. Copper's ability to transfer heat quickly makes it a suitable material for copper plates, pipes and heat sinks.

The thermal conductivity of brass is 109 watts per meter kelvin at 25 degrees Celsius. Generally, this measurement notes the ability of a material to conduct heat through it. Metals such as aluminum and tungsten and alloys such as brass and bronze are relatively thermally conductive.

A 4,000 BTU air conditioner has 4,000 British Thermal Units of cooling capacity, or energy production required to remove heat from a room. This is a very small capacity unit. Window air conditioners normally range from 5,000 BTU to 24,000 BTU.

An air conditioner BTU calculator is software designed to determine the required power of an air conditioner to cool a room based on the specific area and temperature conditions. One BTU (British Thermal Unit) is the amount of energy required to cool 1 pound of water through 1 degree Fahrenheit.

Thermal energy is the movement of particles within matter and is found in the sun, magma, heated water and even the human body. Heat represents the transfer of thermal energy between matter.
