Thermal Conductivity Converter Convert from one unit to another with this easy-to-use conversion tool. Simply select the input or output units, enter your desired value for a conversion, and click on **“Convert”**. The program will immediately return both values after the calculation has finished!

### Thermal Conductivity Converter Definition:

The thermal conductivity of a substance is the rate at which heat moves through it. One watt per meter kelvin **(W.m-1.K-1)** will pass in unit time when its opposite faces differ by one degree Celsius or Fahrenheit.

[su_note note_color=”#11a9fa” text_color=”#FFFFFF”]**For Example,** an insulated wall with low thermal conductivity is like a blanket that doesn’t let through much heat.[/su_note]

Thermal conductivity and thermal resistivity are both key factors in determining the rate at which heat flows from one side of an object to another.

The reciprocal, known as Thermal Resistivity or ohm’s law for electricity–as well as several other equations-are important tools used by physicists when studying mechanics such as elasticity because they can be applied across any kind of cell whose energy changes over time due to stress or strain placed upon them.

## Thermal Conductivity Calculator

A Thermal conductivity calculator is a handy tool that lets you calculate the inherent heat flux of any object, based on Fourier’s law.

This article provides a definition of thermal conductivity, explains how to use the formula for heat flux correctly, and analyzes it in greater detail.

### How to Use the Thermal Conductivity Converter:

The difference in temperature across the object is 20K.

Enter the thermal conductivity of your material in order to find out how much heat it can distribute. [su_highlight background=”#fffc99″]For this example, let’s assume that a brick wall has an equal value of **0.8 W/(m·K)**.[/su_highlight]

The heat flux is determined by Fourier’s law, which can be written as [su_highlight background=”#fffc99″]q = -λΔT/Δx = -0.8 * 20 / 0.35 = -45.71 W/m².[/su_highlight] The symbol **” λ”** represents lambda **(the Greek letter Lambda)**.

A thermal conductivity calculator can be used to find the lambda coefficient.

### Thermal Conductivity Units

You can convert thermal conductivity to SI units with this handy “Conversion Tool“.

The unit for measuring how fast heat moves through something is called the watt per meter (w(m)) Kelvin, or W/(m*K).

You might be wondering what all those numbers and letters mean; don’t worry! Just put them into your favorite calculator as I did below:

**W/(m·K) = (kg·m²/s³) / (m·K) = kg·m / (s³·K)**
