Medical researchers recently performed a study involving 75 women to determine the correspondence between breast volume and bra size. There is a range of variation among wearers of the same letter size. The following volumes in cubic pinkies are the mid-range values, halfway between the extremes of each range.
It happens that in TM a convenient scale for measuring the body is one "centipace" (one hundredth of a pace, 1.61888 centimeters) and this is approximately the width of a pinky finger.
A-----40 cubic pinkies
B-----70 cubic pinkies
C-----130 cubic pinkies
D-----190 cubic pinkies
DD----285 cubic pinkies
DDD---700 cubic pinkies
In other words, for a typical or at least mid-range wearer of size C the volume of each breast is 130 cubic pinkies. A US pint is 112 cubic pinkies, which gives some basis for mental comparison. Size C breasts are apt, in effect, to be more than pint-size. Full results of the study are on the web and readily findable through google.
The use of fingerwidths in measurement has a long and venerable past. The Greek unit was called the *daktylos* and the corresponding Roman unit was the *digitus*.
A cubic pinky is naturally equal to one thousandth of a TM gallon, and also to one millionth of a cubic pace.
