IIRC, Poser figures are limited to the range 0.0 to 1.0, so a 6 foot Don or M2 would be 1.0 unit tall. Very small numbers and painful when used in 3D applications that have unit assignments. So, 1 foot would be 1/6 or 0.166666..., 1 meter is 3.281 /6 or 0.5468 (1 meter = 3.281 ft). Of course, this is assuming that Don or M2 are 6 ft tall. Not an exact science by any measure.
