The SI unit of mass is the kilogram (kg). In science and technology, the weight of a body in a particular reference frame is defined as the force that gives the body an acceleration equal to the local acceleration of free fall in that reference frame.
What is the unit of weight?
newton (N)Therefore, the SI unit of weight can be measured in kg⋅m/s2 (kilograms times metres per second squared) which is equal to a newton (N). Since weight is the force extended by the gravitational force on a mass it is represented by the formula W = m*g, where weight can be kg * m/s2 which is equal to N.

How Much Do You Weigh on Other Planets?
On Earth, for example, your weight is slightly lower on a mountain top than at sea level. The effect becomes even more dramatic for large bodies, such as Jupiter. While the gravity exerted by Jupiter due to its mass is 316 times greater than that of Earth, you wouldn't weigh 316 times more because its "surface" (or the cloud level we call the surface) is so far out from the center.
What is the measure of the amount of force acting on a mass due to the acceleration due to gravity?
Weight is the measure of the amount of force acting on a mass due to the acceleration due to gravity. Weight usually is denoted by W. Weight is mass multiplied by the acceleration of gravity (g).

What happens to the mass of an object if you change your location?
If you change your location with respect to gravity, mass will remain unchanged, but weight will not. For example, your body's mass is a set value, but your weight is different on the Moon compared with on Earth. Mass is a property of matter. The mass of an object is the same everywhere. Weight depends on the effect of gravity.
What is mass in physics?
Mass is defined as the measure of the matter inside a body. In physics, mass is a quantitative measurement of inertia. Let’s understand the concept of mass by understanding Newton's second law.

Weight is expressed in Newton (N) Balance used for measurement. Mass is measured using a pan balance, a triple-beam balance, lever balance or electronic balance.
How is weight measured?
Weight is measured using a scale which effectively measures the pull on the mass exerted by the gravity of the earth. Mass of a body is measured by balancing it equally with another known amount of mass. Mass may be measured using a pan balance while Weight may be measured using a spring balance.
How does the weight of an object depend on the gravity of the object?
The weight of an object depends on the gravity at that place while Mass is always a constant at any place and any time. Eg., If an object's mass is 60 kgs, then its Weight would be 600 Newtons but when taken to the Moon, this object will have a weight of 100 newtonas the gravity of the moon is 1/6th that of the Earth. But the mass of that object will remain the same.

the weight), mis the mass of the object in question, and ais the acceleration due to gravity, on Earth approximately 9.8 m/s² or 32.2 ft/s²).
Is mass a constant or a variable?
Mass can be a constant while Weight varies. External Factors Affecting Weight . Mass is an intrinsic measure of an object and hence is independent of any external factors. Weight, on the other hand, depends on the mass that is attracting it and the force with which it is being attracted. Conversion from mass to weight.
What is the difference between mass and weight?
Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on that object. The difference between mass and weight is the mass is a measure of the amount of matter in an objects, while weight is a measure of the effect of gravity on that mass. In other words, gravity causes a mass to have weight.
What is the unit of mass?

How to tell if a mass has weight?
In other words, gravity causes a mass to have weight. The relationship between mass and weight is a simple equation: W = m * g. Here, W is weight, mass is mass, and g is gravity. People often use the words “mass” and “weight” interchangeably because gravity is pretty much constant on Earth, so there isn’t a difference between their values.
Why is it so difficult to find the difference between mass and weight on Earth?
It can be a challenge to explore the difference between mass and weight on Earth because gravity is all around us. Fortunately, the astronauts on the International Space Station (ISS) conducted experiments that complement activities on Earth.
How to find mass on Earth?
The easiest way to explore mass on Earth is to conduct experiments that move horizontally rather than vertically. This is because objects can’t change their position from the effect of gravity. Build a “mass car” and use an air pump to accelerate the mass across rollers or a low-friction track. Change the mass of the car, make a prediction about how this will change how far the car rolls, and perform an experiment to test the hypothesis. You can graph the distance the car moves compared to its mass. Predict whether the results will be different in space and use the ISS experiment to reach a conclusion.
How do you measure mass?
You measure mass with an ordinary balance on Earth or an inertial balance in space. Weight depends on the effect of gravity, so it can change depending on where it’s measured. In the absence of gravity, weight can be zero. Because weight is a force, it is a vector. It has both magnitude and direction.

For example, a table, a chair, your bed, a football, a glass, and even air has mass. That being said, all objects are light or heavy because of their mass. In this lesson, we will learn what is mass, how to calculate it, ...
How much does Sam weigh on another planet?
Solution: We know that Sam's weight on earth is 1000 lbs and his weight on another planet would be 38% of that on Earth. Therefore, Sam's weight on another planet= 38% × his weight on the Earth = 0.38 × 1000 lbs = 380 lbs. Example 2: The mass of an object is 6,000 pounds. Calculate its mass in tons.

There are various units for calculating mass, like, kilograms, grams, lbs, pounds, etc., but the SI unit of mass is "kilograms" or kg. Every unit of mass can be converted to other units by using a proper conversion formula without affecting the meaning and essence of the quantity to be measured.
A brief history of the concepts of mass and weight
The term ‘mass’ is derived from the Latin massa meaning a lump of dough or paste. In many ancient cultures, despite standardisation of units such as length and volume, different units of weights were used for different goods and measures varied from place to place.
