The formula to calculate the Rack Unit Height (h) is:
\[ h = (1.75 \times n) - 0.0031 \]
Where:
Let's say the number of rack units (n) is 10. Using the formula:
\[ h = (1.75 \times 10) - 0.0031 \]
We get:
\[ h = 17.5 - 0.0031 = 17.4969 \text{ inches} \]
So, the rack unit height is approximately 17.4969 inches.
