Difference Between Mass and Weight
Students of physics often confuse mass and weight of an object and many also feel that there is no difference between the two, while the fact is that there is a lot of difference between the two.
Mass is the amount of matter present in a body and is an intrinsic property of the body. Mass of an object remains the same always at any place.
Weight on the other hand is the force which a given mass feels due to the gravity at its place. Weight is measured in units of Force like Newton (which is the SI unit of Force).
If your mass is 60 kgs then your weight is approximately 60 x 10 = 600 Newtons. This is because
Force = mass x acceleration (From Newton's second Law)
Thus, weight = mass x acceleration due to gravity

Inertial mass is a measure of an object's resistance to changing its state of motion when a force is applied. An object with small inertial mass changes its motion more readily, and an object with large inertial mass does so less readily.
Passive gravitational mass is a measure of the strength of an object's interaction with the gravitational field. Within the same gravitational field, an object with a smaller passive gravitational mass experiences a smaller force than an object with a larger passive gravitational mass. (This force is called the weight of the object. In informal usage, the word "weight" is often used synonymously with "mass", because the strength of the gravitational field is roughly constant everywhere on the surface of the Earth. In physics, the two terms are distinct: an object will have a larger weight if it is placed in a stronger gravitational field, but its passive gravitational mass remains unchanged.)
Active gravitational mass is a measure of the strength of the gravitational field due to a particular object. For example, the gravitational field that one experiences on the Moon is weaker than that of the Earth because the Moon has less active gravitational mass.
Although inertial mass, passive gravitational mass and active gravitational mass are conceptually distinct, no experiment has ever unambiguously demonstrated any difference between them

Weight is define by the product of Mass and Acceleration (Gravitational). It is a force, and the value can be changed as the Gravitational changed, example if you have the pencil put on earth is different in term of weight if you put them on the moon. The unit is in Newton (Name after Sir Issac Newton)
Mass is the property and will not change it forms no matter where the parts are. Mass will remain the same if you are in the space or earth or moon or etc.... Unit is in kg

This isn't a 'scientific' explanation - but it helped my kids to get this concept:
Mass is how much matter there is in an object.
Weight is how hard gravity pulls the object downward.
So an object that has the same mass (amount of matter) has different weight on Earth than it does on Mars, because the gravitational pull on each planet is different.

Mass is the amount of matter present in a body while weight is the force by which the earth pulls us to the ground.Weight will change according to the gravitational force of a place,but mass remains constant.

They are the same when you are on the surface of the earth. However, mass stays the same even in space (relatively speaking), and weight can be anything from nothing at all to quite a bit more than you have here. A larger planet would attract you more strongly than the earth does, and you would weigh more. You would weigh only one-sixth what you do here if you were on the moon. You'd have just as much trouble touching your toes, though . . . more, because of the space suit.

Mass is quantity of matter. Whereas the weight is the gravitational force. If a particular object is taken to the moon its mass will remain unchanged but the weight will be reduced.

mass is the quantity of matter contained in a body.i.e., for eg. iron piece ,
the no. of protons and electrons contained in the body.
weight is the energy required to move that mass against the gravitational force of earth .it will be measured in kgs.also the atomic weight is measured in iron piece.it is the force exerted by the mass on earth.
if we go to moon the mass of the iron piece will be the same, but the weight will be less, since the gravitational force is less in moon by 6 times than that of earth.
if you consider the example of mass and weight in clear terms we should compare earth and moon once again, a wheat flour weighing one kg on earth will weigh only 1/6th on the moon but the mass will be the same on both earth and moon.

The amount of matter contained in a body is mass.
weight is the force (reaction) on your body by the earth.
W=mg where m is mass g is acc due to gravity and W is weight.

weight = mass x gravitational acceleration
w = mg
mass is the property of matter
and weight is a force.
