The user SOMEBODY is really helpful...

F=ma a force is proportionnal to a mass times its acceleration, you have mass in kg and you have acceleration in meters per segonds squate:
A force is measured in newtons: kgm/s^2 or kilograms times meters divised by segonds square, if you get kgm/s^2 you have a force or a measure in newtons!
Edit: the user Jeffrey is very funny;)

Like "Somebody" said, weight is a force and not mass (although the two are often used interchangeably, which is incorrect). The SI unit of force is Newtons, so weight is often measured in Newtons.
Pounds (lbs) are more commonly used as the unit of weight, and the conversion between the two are as follows:
1 N = 0.225 lb.

Newtons is a measure of the force experienced by mass when in the earths (or any other mass) gravitational field.
1 kg experiences a downward force (towards the earths centre) of 9.81 Newtons i.e 1kg weighs 9.81 Newtons although only engineers and scientists say so

Weight is actually a measure of gravity on an object. Since gravity is a a pull, it is measured in newtons. Therefore amoun of force applied to object by gravity is measured by newtons.

weight is a force and we all know that force = mass x acceleration. when we say we weigh 100lbs this is slightly wrong. our weight should be measured in newtons which is the standard unit of force. our mass is a measure of how much matter is within our bodies. i forget what mass is measured in. and here on earth, the acceleration is from gravity. and it's 9.8m/s2. so our mass say 10u times the acceleration gives us a force or weight of 100lbs.

Well, I have a package of Fig Newtons that weighed 1 pound (or 453 grams) when I purchased it...now it probably only weighs about 1/3 of that!

Weight of a body is the force exerted by earth gravity on that body.
Mass is the property of a body because of which it exerts or experiences gravitational force (calculated using Newton's law of gravitation )
When you place a body of mass 1kg on your palm , the body is attracted by earth but is prevented from falling towards earth by your palm .The body exerts a contact force on your palm.The force is equal to weight of the body of mass one kg.
In ordinary language,the force on your palm is 1 kg wt but kg wt is not S.I. unit of force. 1kg wt is equal to 'g' newton or 9.8 newton.
(Newton is name of scientist and newton is S.I. unit of force)
1newton is 1 N

weight is a force. And the SI unit for force is Newton.
just like meter is the SI unit for distance or second is the SI unit for time
