Project Metrication

In view of the continued movement toward metrication, we should
be eliminating archaic English measurements from our calculations.  One
such measurement which is used a great deal in project planning is the
"milestone", derived from two English measurements, the mile (a unit of
distance) and the stone (a unit of mass equal to 14 pounds*).  Converting
to metric equivalents, we find:

    1 mile = 1.609344 km = 1609.344 m
    1 stone = 14 lbs = 6.350288 kg

so that

    1 milestone = 10219.80447 kg-m

or, approximately (if approximations are not too abhorrent to practitioners
of such an exact science as project planning):

    1 milestone ~ 10K kilogram-meters

This suggests derived measurements:  project momentum (milestones per
second)
and project force (milestones per second squared).

Even if metrication is not a priority, there is still a more elegant
reformulation of the milestone as:

    1 Milestone = 28,672 dram-furlongs

Since "dram-furlong" is a somewhat cumbersome appellation, I suggest
"damlong"
as an abbreviation.  Then we could refer to projects which take "2 damlong."

* OK, I know that pounds are weight and kilograms are for mass.  Gimme
  a break!  [:-), Anticipated nit-pick department]
