Body: <p>I know that man-hours are used as a unit to measure time in things like modelling and other work actually done by people, but I also hear man-hours used to refer to graphics rendering time.  How is that measured?  If a video takes 200 man-hours to render, for example, what is that measured against?  Obviously a person could not be expected to perform the mathematics necessary for rendering an image, but all definitions of 'man-hours' that I've been able to find refer to expected output of a human worker in an hour.  How is that measured for things like video rendering which simply can't be done by a human?</p>
