Thermal transmittance - Wikipedia. In most countries, U-value is expressed in SI units, as watts per square metre- kelvin : W/ (m 2 ⋅K) In the United States, U-value is expressed as British thermal units (Btu) per hour-square feet-degrees Fahrenheit: Btu/ (h⋅ft 2 ⋅°F) w/m2k. Heat transfer coefficient - Wikipedia. = the overall heat transfer coefficient (W/ (m 2 ·K)) = the contact area for each fluid side (m 2) (with and expressing either surface) = the thermal conductivity of the material (W/ (m·K)) = the individual convection heat transfer coefficient for each fluid (W/ (m 2 ·K)) = the wall thickness (m).. A Quick and Easy Guide to U-Values - First In Architecture. U-value is the measure of the rate of heat transfer through a component of construction w/m2k. It is calculated in W/m² K, the units of which are based on the rate of heat flow (in Watts) through 1m² of a structure when there is a temperature difference across the structure of 1 degree. Learn how to calculate U-values, why they are important for building regulations, and what are the required U-values for different parts of a building..

. W/m2K is the unit of measurement for the U-value, which is the unit of measurement for the transference of heat through a material. Learn how to calculate the U-value of insulation products and why it is important for energy efficiency and legal compliance in UK construction.. thermodynamics - How do I convert $W/ (mK)$, $W/m^2$ and $W . w/m2k. W/(m2K) W / ( m 2 K) is the heat transfer value. By performing arithmetic on them? Particularly, I have a sum of integrals where each term is multiplied by a constant in one of the given units. And I need to be able to compute the sum so that the units "agree". So as an example consider some heat system governed by:. U-Value Calculator - va-Q-tec w/m2k. The unit of the U-value is W/m²K (watts per square meter and per Kelvin) and indicates the heat flow through an area of one square meter with a temperature difference of one Kelvin (= 1°C) w/m2k. The higher the U-value, the worse the insulation effect, the lower the U-value, the better the insulation effect. The U-value calculator is for guidance.
