There is no "why", because science uses both of those quantities.

Does weight affect mass?
Mass is measured in kilograms, kg and weight is measured in Newtons, N. Weight is the gravitational force acting on an object. F = ma (Newton's Second Law) This can be written as W = mg when calculating weight. W is the force of gravity m is the mass in kg g is the acceleration due to gravity, 9.8 m/s2 Example: What is the weight (gravitational force) of a 100 kg man? W = mg = 100 x 9.8 = 980 N Mass and weight are two different measurements in science but we generally use them to mean the same when not in the science lab.
What is the science term density?
Mass (or weight) per unit volume.
Why do scientist use mass instead of weight?
The word weight in every day speech means how much do you weigh converted back to mass. That is if I ask "what do you weigh?" but I want the answer in pounds or kilograms.In science mass is measured in kilograms (or pounds outside the science lab) but weight has more to do with the gravitational pull of the Earth.Newton's second law is F = maForce = mass x accelerationWeight = mass x acceleration due to gravityW = 50 kg x 9.8 m/s2 (Force or Weight has a unit of Newtons, N)= 490 NWhy? Perhaps because when we use the balance or the weighing machine we are using gravity but then we convert the scale back to mass.
What are science facts about weight?
you can measure weight by a scale. weight could change from place to place like if you go to the moon you will weigh less because there is less gravitational pull on you. it basically depends on mass and mass is the amount of matter an object is made of. mass does not change so on the moon your mass does not change it's your weight that changes
What is weight in physics?
Weight is gravity's effect on mass. That is why weight is not generally used in science, because it varies slightly at different places on Earth, and differs tremendously on other celestial bodies and is zero in space. Mass is a constant.
How do math and science interrelate?
You can use mathematical formulas to determine measurements of mass, force, weight, wavelength, etc.
What is a sentence for the word weight in science?
In science weight means the heaviness or mass of an object. It is determined by the local acceleration of gravity times the mass of the body.

Sixth grade science question what is mass?
Mass is the weight of the object without the gravitational force acting on it..........
How does science play a role in gymnastics?
it involves physics, which depend on mass and weight.
Mass is used than weight by scientists?
English the language the speak of science.
Why do scientist measure and record the mass other than the weight?
The mass is a measure of the amount of matter present in an object whereas weight is a measure of the force on the object due to gravity. Weight is measured in Newtons, mass is measured in kilograms (pounds in the Imperial system) When we use the term weight outside of science we actually are referring to mass. mass is a measure of 'stuff,' of material that makes up an object. weight is the gravities affect on mass as you can see from the equation Fg=mg, m=mass g=gravity (on earth it is 9.8) and fg is weight in newtons

How do you find out a weight in mass?
You use the formula weight = mass x gravity. In SI units, the gravity is 9.8 meters per second square, weight is in Newtons, mass is in kilograms.You use the formula weight = mass x gravity.

How do you get weight if you know the mass of something?
Use the advanced search tool and search on weight and mass.
How do we use weight?
Usually we do not. We use mass, but wrongly call it weight. You compare the masses of people, you buy fruit and vegetables, or meat by their weight and not mass, etc.
