Hmm... Something doesn't... sound right here, folks. If not, let's see. 1 milliquad is 1/1000 of 1/4 of a circle, or 90/1000 degrees. If a full circle has 2 pi, 90/1000 degrees is equivalent to 1.57 "units", not .785:
(90/1000)/360 x 2 x pi So, I'm afraid that Pat's figure is half what it should have been...
