what is the SI unit of mass?

Answer 1

Kilogram.

Answer 2

Kilogram, not gram a comon misconseption, the kilogram is the standard unit since not to may things are so small they could be massed in grams... the direct translation to our version is that most things are to heavy to be wieghed in ounces so we use pounds, also it could get to confusing between a liquid and wieght ounce so we tend to use ounce less (but no relation to the fact that kilogram is used as the standard insted of gram)

Answer 3

Think of it this way...
for several equation/forumlas, mass has always been what?
newton's law: M=FA, where M=mass, F=force, and A=acceleration...and mass, as we know it to be, is always in kilograms (kg).
potential gravitational energy = MGH where M=mass, G=gravitational force, and H=height...once again, mass is always in kg.
HOWEVER, this must NOT be confused with what we do in chemistry, where we calculate masses in grams!!! SI is more associated with physics, not chemistry...so remember mass as SI unit is KG, not G.
