Mass and weight are two different things. It does not make sense to ask which is more accurate.
Mass is used to measure an object's ability to resist a force. f = ma, or m = f/a.
Weight is used to measure an object's force applied due to gravity. Measured in newtons, f = ma, or newtons = kilograms time 9.81 meters per second squared.

How does one know if measurement is precise or accurate?
because of the mass
How do you balance a see saw with one mass on one side?
if seesaw is balanced under its own weight with no added mass on it you cannot balance on one side. If it is unbalanced under its own weight u can add mass to balance on one side with mass depending on distance to pivot
How do you calculate mass if you are only given weight in Newtons?
Weight = (mass) x (local acceleration of gravity). Mass = (weight) / (local acceleration of gravity) If you know the weight and the local acceleration of gravity, you can calculate the mass. Anywhere on or near the surface of the earth, the local acceleration of gravity is about 9.82 meters per second2 . As an example, an object with a weight of 9.82 newtons has a mass of one kilogram.
Which is more common a mass of zero or a weight of zero?
Depend on what exactly do you mean by 'common'. On one hand there are countless photon everywhere which has zero mass. But if you mean everyday objects, then zero weight of cause (free fall, space etc), as I don't think zero mass is even attainable at this scale.
Is mass an accurate measure of weight?
Absolutely not. Mass and weight are two entirely different things. Every object has a mass which is a measure of the amount of matter that it contains. It is a property of the object and is essentially a constant. I say essentially because radioactive decay (and fusion is stars) can alter the mass of an object by converting some mass into energy or the other way around.Weight, on the other hand, is a measure of how that mass is affected by gravitational attraction. On the surface of the earth, a mass of one kilogram will have a weight of approximately 9.8 Newtons, but on the moon, the same kilogram will have a mass of only a sixth as much because the moon's gravity is so much weaker. On a neutron star, on the other hand, the same kilogram mass, would weight about 200 billion times as much as on earth. In outer space, it could be weightless.
Is molecular weight the same as mass?
Technically... not really. It would perhaps be more accurate to use the terms formula mass and molecular mass rather than formula weight and molecular weight. This because in physical terms, weight is a force while mass is a measure of the amount of substance in something.
Would using a pipet to determine density be more accurate?
A pipette is quite accurate. So yes weighing the contents of one into a vessel to get the weight (mass) would be an accurate way of measuring density.
What one has more mass an atom of gold or lead?
The atomic weight/mass of Lead is 207.19 --- --- --- The atomic weight/mass of Gold is 196.96655 --- --- --- --- --- --- Therefor Lead has more mass.
Why is weight different from mass?
Well mass is different from weight in one major way. Mass is how easily something can lift more than weight being how heavy an object is. For example a balloon has mass, but a person carries weight.
How completely accurate are bmi calculators?
BMI calculators are not completely accurate as it does not take account for bone density and weight of other organs in one's body. It is normally used as and estimate gauge to measure one's mass.
Where can one find an accurate weight converter?
An accurate weight converter available online is to type in the specifics of what weight conversion someone is looking for and do a search until one is found.
The mass of abody measured by two persons is 10.2kg and 10.23kgwhich is more accurately measured and why?
The "10.23" measurement is more precise, but we have no way of knowing which one is more accurate.
Is 155 overweight for a 5' 4 person?
Check your BMI (body mass index) for your BMI, be aware this is sometimes not accurate if you are muscular. Also look for one with weight, height, age, and date of measurements, for the most accurate calculation
What is more likely an object's weight is 0 or an objects mass is 0?
maybe air or gas i think for weight...... : Actually, the above have weight and mass, if they are on or about Earth. Anything that is matter will always have mass. It may have no weight if it is in free fall. Light, or photons, have no mass. One may say - very carefully - that you could consider they have "weight" at times, if one is applying that term to the phenomena of gravity affecting those photons.
Are you fat if you weigh 119 pounds and you're 11 years old?
I am 15 and I weight 155 and I am considered at risk. From what I have found 111 is very health if you are about 5'6" and a boy. But since you didn't post your height that isn't accurate. To get a more accurate calculation use a BMI (body mass index) calculator. To find one google BMI for Teens. For the most accurate calculation find one that requires weight, height, age, and the date of measurement. Remember if you are muscular this may not be accurate
What is the mass of one kilogram?
1 cubic decimeter of pure water is 1 liter and weigh 1 kilogram. A mass of one kilogram is a weight of one kilogram at sea level. If you move your subject into space, it will weigh less. If you take it to Jupiter, it will weight more, but its mass will remain one kilogram.
Which one weight or mass is changed by gravity?
Weight depends on the strength of gravity. Mass is constant.
