what is mass, like kilograms and all that stuff, what types of grams are in mass?

In science, mass is the amount of matter an object has. Newton's second law says that mass is the property of matter that determines the force required to impart a given acceleration to an object.
how do you measure mass?
Shut it -- please use a more acceptable screen name.
Mass is the absolute amount of matter within an object. Weight is how much gravity is being put on an object and because of this, you would weigh less on the Moon than on Earth since there is less gravity. To measure mass you need to use the formula M = V*D or mass = volume times density. You can measure this by just putting an object on a scale since Earth has a gravitational pull of 1 G.

As others above said, mass is a measure of the amount of matter, pretty much proportional to the number of protons and neutrons on your scale. It is the same on earth, moon, or wherever.
As was also said above, we usually measure "weight" which is mass times the acceleration of gravity, g. Force is expressed in Newtons and is the mass times acceleration.
The scientific unit of mass is a kilogram which is one thousand grams, one million milligrams.
On earth g is about 9.81 m/s^2
If you put a one kg mass on a scale on earth, the force measured is 9.81 Newtons. Of course the scale says one kg because it is only designed to work on earth. It really should say 9.81 Newtons.
In English units the force measure on earth is a pound. You divide that by about 32.2 ft/s^2 to get the mass in slugs.
