The physical quantity of weight is Newton (N). Weight shares the same SI unit as force. ;)
Not so. The measure of the quantity of matter in an object is its mass. The weight
of the same quantity of mass can change in different places and circumstances, but
the mass can't.
The force that gravity exerts on a given mass.
Gravity = 9.8 m/s^2
F = M*A
Weight = Mass * Gravity
That is why your WEIGHT is different on the moon, but your mass will always be the same.
Mass is a scalar, hence only has a magnitude (kilograms, kg). Weight is a vector (its a force - measured in Newtons, N) and so also has a direction. If your answering a weight question give a direction. Usually 'down' will suffice.
There are four main ways to measure a quantity of matter: by [1] mass, [2] weight, [3] volume, and [4] the number of particles (molecules, atoms, or subatomic particles). Examples of units of measure for these four categories are as follows:
[1] MASS: kg (kilogram), g (gram), t (tonne), lbm (pound-mass), slug (slug), ton (ton), u (Atomic Mass units)
[2] WEIGHT: N (newton), dyn (dyne), lbf (pound-force), kip (kilopound)
[3] VOLUME: m^3 (cubic meter), L (litre), ft^3 (cubic foot), gal (gallon), tbsp (table spoon)
[4] NUMBER OF PARTICLES: mol (mole)
Note: One mole contains 602 214 179 300 000 000 000 000 particles. One mole of water has a mass of 18 g and a volume of 1.2 tbsp (about one spoon full of soup).
Note: The units listed in bold font above are the standard units used in most science and engineering work and are called the SI system of units. However, many branches of science, and most branches of commerce, have their own preferred set of units that differ from the SI set.
the amount of matter is called mass, weight is how much I am pulled down by the gravity of the earth
in outer space, I still have the exactly same mass because I didn't lose my body matter, yet I am weightless!
No, because:
Mass refers to the amount of matter (stuff) an object has.
Weight is a measure of the force of the gravitational attraction between the object and Earth.
Example: The same rock that weighs 300 pounds on Earth would weigh about 1/6, or 50 pounds, on the moon or be weightless in space. In all three situations though, while its weight would differ, its mass (amount of matter or stuff) would remain the same.
However, if you have an object of known, standard mass in a standard gravitational field, you can compare other objects to it. The ratio of the weights will equal the ratio of their masses.
Weight is a measure of the force of gravity acting on an object due to its mass. It is typically measured in units such as kilograms or pounds.

Is weight an example for a quantity Which has direction but is not a vector?
Weight is not a vector quantity because it lacks direction. Weight is a scalar quantity that only has magnitude. It is the force exerted on an object due to gravity, always directed towards the center of the Earth, but it is not considered a vector because it does not have directionality in the way vectors do.
Why is weight a vector quantity?
Weight is a vector quantity because it has both magnitude (amount of force acting on an object) and direction (towards the center of the Earth). It is determined by the mass of an object and the acceleration due to gravity, which can vary depending on the location.
Is height a scalar or vector quantity?
WEIGHT is a VECTOR quantity .. because the weight has the direction into the surface of the earth to the down effected by the gravity .. but mass is a scalar quantity like 90 kg .. so .. WEIGHT IS VECTOR ..
What is the force with which gravity pulls on a quantity of matter is reffered to as?
The force with which gravity pulls on a quantity of matter is referred to as weight. Weight is the result of the gravitational force acting on an object's mass.
Is weight derived physical quantity?
Answer: No, weight is not derived from any other quantity. It's a characteristic of something. You might be thinking that mass would be preferable since that does not vary with the gravitational pull exerted on the item being measured. Answer: It really depends on the system of units used. In the SI, a weight is a force, and therefore a derived quantity (the product of a force and an acceleration).
Is weight is a sc alar or vector quantity?
Weight is a vector quantity. Weight is the mass of a body times the acceleration due to gravity, which is a vector quantity. Weight is in the downward direction.
What is the weight of glycol?
The weight of glycol will depend on the quantity!

What is the definition of quantity?
Quantity means the amount of something (number, weight, or volume).
How do you calculate the quantity of sand in 1 cubic meter?
"1 cubic meter" is a perfectly good 'quantity'. If the 'quantity' you want is the weight instead, then you need to know a unit weight or density for sand, in order to convert a volume to a weight.
Why is weight a vector quantity?
Weight is a vector quantity because it has both magnitude (amount of force acting on an object) and direction (towards the center of the Earth). It is determined by the mass of an object and the acceleration due to gravity, which can vary depending on the location.

Are weight length time and mass fundamental quantities?
No, weight is not a fundamental quantity.
Is specific weight is a dimensionless quantity?
energy/mass example: calories/gram
What is the weight of demineralised water?
The answer will depend on the quantity of water.
What is the physical quantity of weight?
Weight is a measure of the gravitational force acting on an object due to its mass. It is typically measured in units such as pounds or kilograms.
Is platinum's weight 195 grams or kilograms?
The weight cannot be 195 grams nor kilograms because these are measures of mass, not weight.The weight will depend on the quantity of platinum and the force of gravity.The weight cannot be 195 grams nor kilograms because these are measures of mass, not weight.The weight will depend on the quantity of platinum and the force of gravity.The weight cannot be 195 grams nor kilograms because these are measures of mass, not weight.The weight will depend on the quantity of platinum and the force of gravity.The weight cannot be 195 grams nor kilograms because these are measures of mass, not weight.The weight will depend on the quantity of platinum and the force of gravity.
