SWR is nothing more than a dimensionless impedance ratio.
Is that so... Owen

Yes, it is so and it is equal to:
SWR = (A + B)/(A - B)
Whe
A = sqrt ( (R + Z)^2 + X^2 )
B = sqrt ( (R - Z)^2 + X^2 )
R = resistive component of load impedance in Ohms.
X = reactive component of load impedance in Ohms.
Z = reference impedance (purely resistive) in Ohms
If you don't believe it, get some resistors, capacitors and a half
way decent SWR meter and do some experiments; no transmission line
required.
