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 = ma
Force = mass x acceleration
Weight = mass x acceleration due to gravity
W = 50 kg x 9.8 m/s2 (Force or Weight has a unit of Newtons, N)
= 490 N
Why? Perhaps because when we use the balance or the weighing machine we are using gravity but then we convert the scale back to mass.

Scientists use mass instead of weight because mass is an intrinsic property of an object that remains constant regardless of the object's location. Weight, on the other hand, is a measure of the force of gravity acting on an object, and it can vary depending on the object's location in the universe. By using mass, scientists can have a consistent measurement of an object's quantity of matter.

Why don't scientist use weight instead of mass as a measurement?
Weight is a measure of the gravitational force acting on an object, and can change depending on the strength of gravity. Mass, on the other hand, is a measurement of the amount of matter in an object and is independent of gravity. Scientists use mass as a measurement because it remains constant regardless of the location of the object in the universe.
Why do you use mass and not weight in science?
In science, mass is used instead of weight because mass is a measure of the amount of matter in an object, while weight is the force of gravity acting on an object. Mass remains constant regardless of location, while weight can vary depending on the gravitational pull. By using mass, scientists can ensure consistent measurements and comparisons across different environments.
What units would you measure the weight of a pencil in?
The units grams would be a good choice.
What to scientist use to measure mass?
They use a tri beam scale.
How do you find the weight when you know the mass?
To find weight when you know the mass, you can use the formula Weight = Mass x Acceleration due to gravity. Simply multiply the mass of the object by the acceleration due to gravity (usually taken as 9.81 m/s^2) to calculate the weight in newtons.

Does the shape of an object determine mass?
No. Mass is the weight of an object on earth. Scientists use mass instead of weight so the measurements will be the same everywhere. For example A big ballon has a relatively lower mass than a small sized stone
Why do scientist use the unit mass instead of saying weight?
Mass doesn't change where ever the object or thing is but weight changes depending on where it is(depends on acceleration due to gravity-g) Eg: Mass of object doesn't change either it is on moon or earth but weight changes(on moon it is 1/6 of that on earth).
Do scientist use mass as a measurement?
yes
Why do scientist use weighted average instead of straight mathematical average of masses of isotopes to indicate the atomic mass of an element?
The percentage of each isotope is different.
What do scientist use to measure mass?
They use a tri beam scale.
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
Life Scientist use kilograms when measuring an object's .?
mass
Which instrument would a scientist use to out an exact mass of a dry chemical?
A Scientist would use a balance, either triple-beam or electronic.
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.
