Valid formulae for tidal locking timescales

[Linguofreak]

I've been trying to find a formula to determine the tidal locking timescale between two bodies, and haven't been having much luck. I've found a few formulae that claim to do the job (two from Wikipedia), but so far they're dimensionally bogus: one gives me units of angle * time, another gives distance^6 / mass^2 *time, and another gives me distance^6 / mass^2. Does anybody know of a formula that actually gives an answer in the correct dimensions, or can anybody advise me on how to turn the formulae here into dimensionally correct formulae (is there even enough information in the article to do so?)?

Units work out to seconds in the formula for me. (Note that radians are dimensionless; when you multiply radians by a distance (radius), you get distance (arc length).)

w => s^-1
a => m
I => kg*m^2
Q => unitless
G => m^3*kg^-1*s^-2
mp => kg
k2 => unitless
R => m

so you get:
s^-1*m^6*kg*m^2
--------------------
m^3*kg^-1*s^-2*kg^2*m^5

Reduces to seconds
