## What is symbol for thermal conductance?

A measure of the ability of a material to transfer heat per unit time, given one unit area of the material and a temperature gradient through the thickness of the material. It is measured in **watts per meter per degree Kelvin**.

## What is symbol for thermal conductance?

Thermal conductivity (often denoted by **k, λ, or κ**) refers to the intrinsic ability of a material to transfer or conduct heat.

## Why is the unit of thermal conductivity?

**The transfer of heat energy is defined as heat flux, Q**. By definition, this is the flow of heat energy through a defined area over a defined time. So, the units for Q are Joules (energy) divided by area (square meters) and time (seconds).Jul 29, 2018

## What is the SI unit of thermal resistance?

The SI unit of absolute thermal resistance is **kelvins per watt (K/W)** or the equivalent degrees Celsius per watt (°C/W) – the two are the same since the intervals are equal: ΔT = 1 K = 1 °C.

## What is the unit of thermal conductivity Mcq?

**WmK−1**.
