If you have 1 billion atoms of hydrogen, it is still 1 billion atoms of hydrogen whether its on Earth or on the Sun's surface.
OK, than enlighten me and tell me what number you will put into E=mc2 for mass of those 1 billion atoms of hydrogen

Approx 1.67*10^-15 grammes.That's it's mass which is constant wherever it is in the universe, the weight will change according to gravity.
The gram was originally defined in 1795 as the mass of one cubic centimeter of water at 4 °C, making the kilogram equal to the mass of one liter of water. The prototype kilogram, manufactured in 1799 and from which the current kilogram is based, has a mass equal to the mass of 1.000025 liters of water.

Weight = mass x acceleration of gravity
1kg x 9.8m/s2
So 1kg weighs 9.8 Newtons.
The joule is equal to the energy expended (or work done) in applying a force of one newton through a distance of one metre, or in passing an electric current of one ampere through a resistance of one ohm for one second.
The Avogadro project has attempted to produce a new standard 1kg mass, which is based upon the number of silicon atoms in a crystal defined by 35.74374043 moles of silicon 28. This prototype is designed to be a true representation of 1 kg.
this is an arbitrary number to describe the observed
...thinking about it, where does this spend energy comes from ???
it's a weight after all... a number of atoms to describe something, a volume of something in designated environment...
***
Volume is the quantity of three-dimensional space enclosed by some closed boundary, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains.

Your whole post is as if a dog ate a few physics textbooks and blew chunks afterward.
wait till the dog #s it out, may be a nicer outcome
I can also tell you what causes this delay... but not here and now
Ah yes... The ol, "Mysterious answer to the mysteries of the universe that only I have but I can't tell you right now..."
"A number of atoms to describe something" or more appropriately the number of atoms making up an object is its mass. Not its weight. Volume is a separate calculation of how much space the object takes up:

NO, it's no the answer but maybe a solution
depend who want to listen
YES.. it is more complex than few words
NO, this is the confusion...
it's not about measurement in given environment, this environment distorts the measurement
you need to understand that an atom has different properties in different field strength.
not just the mass, but also the behave

1.67*10^-15 g is correct.
1.673x10^-18 kg and 6.166058x 10^-17 kg are wrong.
As for the mass and weight? I don't see how you can get confused about that?

So you are saying that mass can change under different conditions or different fields?
What spent energy are you talking about? Gravitational force? You have to lift the object in the air for it to come back again. So whatever expended energy to get it that high, kinetic energy, is transferred as potential energy, and then again to kinetic energy when it's falling.
YES, if matter counteracts the acceleration of gravity it is doing work ! It spent energy, real energy ( and not QM demons that don't want to be at the same place at the same time)
