An LC platform mode starts as an exact product and reciprocal. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Inductance times capacitance gives a time square
The inductance is 1 henry and the capacitance is 1 farad, so the product is 1 square second.
1H⋅1F=1s2
The checked mode uses frequency square
The normalized mode has frequency square 1 per square second. No square root or microwave frequency is claimed.
