LEGACY_K_THERM_RES

Backward-compatible wrapper that computes thermal resistivity from thermal conductivity. It preserves legacy naming while returning the same reciprocal material property.

The conversion is:

r = \frac{1}{k}

Excel Usage

=LEGACY_K_THERM_RES(k)

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

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

Example 1: Example resistivity

Inputs:

k
0.25

Excel formula:

=LEGACY_K_THERM_RES(0.25)

Expected output:

4

Example 2: Higher conductivity

Inputs:

k
2

Excel formula:

=LEGACY_K_THERM_RES(2)

Expected output:

0.5

Example 3: Lower conductivity

Inputs:

k
0.1

Excel formula:

=LEGACY_K_THERM_RES(0.1)

Expected output:

10

Example 4: Moderate conductivity

Inputs:

k
0.5

Excel formula:

=LEGACY_K_THERM_RES(0.5)

Expected output:

2
