Thermal Conductivity Converter • Thermodynamics — Heat

Converter provides units and measures conversions. For scientific, educational and general purposes to convert from one unit to another. For science and education It is the number of Watts per square metre of the construction, per degree of temperature difference between one side and the other (W/m2K). As a rule of thumb, the lower the U-value the better, because the complete construction transmits less heat energy. We work closely with all our suppliers to provide specialist advice and support Thermal conductivity (W/mK) Material thickness (mm or metres) To get the 'R' value, you divide the thickness (metres) by the thermal conductivity (W/mK). Example. 200mm Loft Roll with 0.044 W/mK = .2m/.044W/mK = 4.545 m2K/W; The U value of the element is then 1/R. Example = 1/4.545 = 0.22 W/m2.K The U-Value is measured in W/m² K. This is broken down as: The rate of heat flow (in Watts) through 1m² of a structure when there is a temperature difference across the structure of 1 degree (K or ˚C) Example: Wall 1 with U-Value of 0.3 W/m2 K will lose heat at half the rate of Wall 2 which has a U-Value of 0.6 W/m2 K

  2. This is expressed as m2K/W. If the material consists of several elements, the overall resistance is the total of the resistances of each element. The higher the R-value, the more efficient the insulation. Example: PIR Board: 0.022 W/mK and 100mm thick; R-value = 0.1 metres ÷ 0.022 = 4.54 m2K/
  3. W/mK stands for Watts per meter-Kelvin. It's also known as 'k Value'. The comparison of thermal conductivity can be measured by the 'k' value. The k value, or Thermal Conductivity, specifies the rate of heat transfer in any homogeneous material. If a material has a k value of 1, it means a 1m cube of material will transfer heat at a rate of 1 watt for every degree of temperature.

Kilocalorie/Hour Square Meter °C : The kilocalorie per hour per square meter per degree Celsius is a unit of the heat transfer coefficient. Its symbol is kcal/h•m²•°С. It is equal to 1.163 watt/m²•K. Watt/Square Meter K : The watt per square meter per Kelvin is a SI derived unit of the heat transfer coefficient. Its symbol is W/m²•K °K can be replaced by °C in all of the above since those degrees are the same size. in. is the abbreviation for inch(es), and ft for foot (or feet). kcal is kilocalories. The values of the Btu and calorie are those of the International Table. Very large and very small numbers appear in e-Format and are not spaced. Unvalued zeros on all numbers have been suppressed W/mK is a measure of thermal conductivity, i.e. conductance per meter measured in Watts /meter * degree Kelvin. Resistivity, the resistance per meter is the inverse of this. R is a measure of thermal resistance for the thickness of material concerned (for the example you gave 70mm, or 0.07m). Resistance = resistivity * thickness

Normally film coefficient values are given in BTU/hr/ft2/F or W/m2/K. You'd like to convert the values when units are given in BTU/hr/ft2/R. R stands for Rankine and is on the same scale as Fahrenheit (F) just like Kelvin (K) is on the same scale as Celsius (C). Therefore BTU/hr/ft2/R is the same unit as BTU/hr/ft2/F and the following conversion can be used: 1 [BTU/hr/ft2/R or BTU/hr/ft2/F] = perform conversions between Thermal Conductivity units. How to use Thermal Conductivity Converter Select the unit to convert from in the input units list. Select the unit to convert to in the output units list.
