How fast does human hair grow in MPH?

Wow. I grossly miscalculated my first guess.

The correct answer is: (approximate) 1.11347E-8 MPH.

=

(Using dimensional analysis): .5/(29.53*12*5280*24)

..that is: (.5 inches of growth per month) * (1 month per 29.53 days) * (1 foot per 12 inches) * (1 mile per 5280 feet) * (1 day per 24 hours) = equals units of Miles per Hour.

thanks for the pickup!
