According to http://en.wikipedia.org/wiki/Mass#Weight_vs._mass Wikipedia:
In everyday usage, mass and "weight" are often used interchangeably. For
instance, a person's weight may be stated as 75 kg. In a constant
gravitational field, the weight of an object is proportional to its mass,
and it is unproblematic to use the same unit for both concepts.

Body Mass Index, Muscle Mass, and Bone Mass are already parlance
understood and accepted by “common people” in the US.
There is no good reason to avoid the term Body Mass for persons or
simply Mass when mass in intended for any object.
The fact that all sectors in the US do not yet understand and accept
all elements of SI does not grant any of us permission to perpetuate
corrupted use of SI!
The gram and kilogram are unambiguously “mass” in SI.
There is even a CGPM Resolution intended to clear this historical
confusion of the quantity names “mass" and “weight" and their
respective
SI units “kilogram" and “newton”;
Let’s not contribute to the continuation of this confusion!

Driver License says weight, which is the term common people use in the
context of how much we weigh. Do you think encouraging Americans to say
mass instead of weight will be an incentive or a turn off in our battle
to win them over to SI?

Harold,
Please remember that the kilogram is the unit of *mass* in SI.
Weight is a force measured in newtons, as are thrust, lift, and
drag in the flight of an aircraft,
Body mass is always measured in kilograms by well informed
medical professionals.
In this age of space exploration, kilograms and newtons must
not be confused, even in the minds of elementary pupils.

Thanks for the link. Here is what I just posted there:
No one is a foreigner when you consider Earth your home Metric System
became International System in 1960. People who are mathematically
literate know the International System simply by SI which is its
symbol. American Scientists already use SI. Our United States Dollar
is already decimalized, so no change is necessary there. Nutrition
Facts Labels are already in grams. For decades, our Wine & Distilled
Spirits have already been exclusively measured in metric units (750
mL is the most common size) so do you see confused, angry Americans
go on perpetual mass riots to protest the lack of ounces on the
label? Of course not! The U.S. military uses metric measurements
extensively to ensure interoperability with allied forces,
particularly NATO Standardization Agreements. Ground forces measure
distances in klicks, slang for kilometers. Most military firearms are
measured in metric units, beginning with the M-14 which was
introduced in 1957. Heavy weapon caliber is measured in millimeters.
We have been using metric tools for many years. You probably have
metric tools in your garage right now. It is easy to adjust to
degrees Celsius; just remember this simple little rhyme: 30 is warm;
20 is nice; 10 is cold and 0 is ice. Our prescriptions are already
measured in metric units (mg, mL et cetera). A4 is the most commonly
used paper size in the world. Your computer printer paper tray has an
adjustment to accommodate A4 which is a little taller and a little
narrower than what you are used to. By 1975 so many countries were
using A4 that it was established as an ISO standard, as well as the
official United Nations document format. Basically, all we have to do
is measure our weight and height in kilograms and centimeters and
change our road signs and GPS setting to metric units. You probably
already have kilometers per hour on the speedometer of your vehicle
right now. No one is a foreigner when you consider Earth your home.
Measuring is the Path to Knowledge and Understanding.
