LEGACY_THERM_RES_K

Backward-compatible wrapper that computes thermal conductivity from thermal resistivity. It keeps legacy naming while using the same reciprocal conversion.

The conversion is:

k = \frac{1}{r}

Excel Usage

=LEGACY_THERM_RES_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:

=LEGACY_THERM_RES_K(4)

Expected output:

0.25

Example 2: Lower resistivity

Inputs:

r
2

Excel formula:

=LEGACY_THERM_RES_K(2)

Expected output:

0.5

Example 3: Higher resistivity

Inputs:

r
10

Excel formula:

=LEGACY_THERM_RES_K(10)

Expected output:

0.1

Example 4: Moderate resistivity

Inputs:

r
1.5

Excel formula:

=LEGACY_THERM_RES_K(1.5)

Expected output:

0.666667
