THERM_RESIST_TO_K

Converts thermal resistivity to thermal conductivity by taking the reciprocal. This is used when resistivity is available in material data but conductivity is required for model inputs.

The relation is:

k = \frac{1}{r}

Excel Usage

=THERM_RESIST_TO_K(r)

• r (float, required): Thermal resistivity (m*K/W).

Returns (float): Thermal conductivity (W/m/K).

Example 1: Example conductivity

Inputs:

r
4

Excel formula:

=THERM_RESIST_TO_K(4)

Expected output:

0.25

Example 2: Lower resistivity

Inputs:

r
2

Excel formula:

=THERM_RESIST_TO_K(2)

Expected output:

0.5

Example 3: Higher resistivity

Inputs:

r
10

Excel formula:

=THERM_RESIST_TO_K(10)

Expected output:

0.1

Example 4: Moderate resistivity

Inputs:

r
1.5

Excel formula:

=THERM_RESIST_TO_K(1.5)

Expected output:

0.666667
