K_TO_THERMAL_RES

Excel Usage

=K_TO_THERMAL_RES(k)

• k (float, required): Thermal conductivity (W/m/K)

Returns (float): Thermal resistivity (m*K/W)

Examples

Example 1: Thermal conductivity of 0.25

Inputs:

k
0.25

Excel formula:

=K_TO_THERMAL_RES(0.25)

Expected output:

4

Example 2: High thermal conductivity

Inputs:

k
10

Excel formula:

=K_TO_THERMAL_RES(10)

Expected output:

0.1

Example 3: Low thermal conductivity

Inputs:

k
0.05

Excel formula:

=K_TO_THERMAL_RES(0.05)

Expected output:

20

Example 4: Copper conductivity

Inputs:

k
400

Excel formula:

=K_TO_THERMAL_RES(400)

Expected output:

0.0025
