Weight is measured in Newtons because it is a force. When an object is in a gravitational field, it experiences a force due to gravity, which is what we refer to as weight. Kilograms, on the other hand, are a measure of mass, which is an intrinsic property of an object and measures the amount of matter it contains. While weight and mass are related, they are not the same thing, hence the need for separate units of measurement.

Because of sir Issac newtons law #2 of force and mass. F(force)=ma(mass times acceleration) F=ma.

What is weight usually measured in?

Weight in a scientific form is measured in Newtons (N). Which is derived from the equation F=ma. Mass in the other hand is in more common use to most people and is usually measured in Kilogrammes (Kg) or Pounds (lbs), or stones and pounds (st & lb).

How much is 300Newtons in mass?

Mass isn't measured in newtons. Force is. 300 newtons is the same as a force of about 67.5 pounds. It's the weight of about 30.6 kilograms of mass on earth.

How do you find force if you have the weight?

Weight is a force. It is described as the gravitational force acting on an object. It is measured in newtons. If you are thinking of the mass (measured in kilograms for instance) then you multiply by the acceleration due to gravity. Weight = g x mass.

Is weight measured in pounds or newtons?

'Weight' is a force, and can be described with any unit of force. 'Newton' is the unit of force in the SI system. 'Kilogram' is a unit of mass, not force. The weight of an amount of mass is always the same as long as it stays on the same planet. But when that same mass leaves the Earth and goes to other places, then its weight changes. Since all of human history so far has taken place on the Earth, a lot of people have gotten used to describing weights in terms the mass that has that weight on Earth. According to that habit, 'one kilogram' is the same as 9.8 newtons of weight, or 2.205 pounds of weight. But it's not a good habit, and now that we're beginning to do things in other places away from the Earth, the folks who are in that habit are going to have trouble. They'll be shocked the first time they're someplace where 1 kilogram doesn't 'weigh 1 kilogram'.

What is the measure of the force of attraction between objects due to gravity called?

The force of gravity between two objects is measured in newtons. This is no different, technically, than what weight "should" be measured in. We use pounds and kilograms, but we should be using newtons, to be scientifically correct.
