I did not say the g in kG is gravity i said you can not get kg with out using g ? twisting words will get you nowhere as its up there for all to see.

I never said you did.

I was just making sure that is clear.

You said you cannot get kg without using g. Care to back that up?

an object with a mass of one kilogram has a weight of about 9.8 newtons ? guess what 9.81 N is ?

Yes. That is right. An object with a mass of 1 kg. No G required.

9.81 N is a measure of force, which can be the force due to gravity, but it isn't measured in kg.

The main point is you can not use kg unless you acknowledge gravity is in the equations you use.

Sure you can. Chemists/physisists use it very often, almost every time they do EDS or MS.

Both are based upon the mass of the particle in question and completely ignore gravity.

Even some density meters function completely independently of gravity.

So no, I can use kg without using gravity at all.

When it come to buoyancy we use pressure e.g. 1 ATM or 1G as a base reference. Are you seeing a pattern ?

No. We do not use 1 G as a reference. We use 1 atmosphere. Again, pressure can be measured completely independently of gravity.

In fact, the standard unit is Pa, which is 1 kg m/s^2.

But yes, I am seeing a pattern, you trying to stick gravity in where it isn't needed.

same for density SI unit kg/m3 >>> kg ? https://en.wikipedia.org/wiki/Density

Yep, same for density. No gravity required.

Gravity is everywhere in every calc its the base unit of everything were talking about.

Really? Because so far the only calc you have "provided" is to determine the weight due to gravity of an object.

It is the base unit of no SI unit.

So no, it isn't in everything we are talking about.

Do you know what this word means >> "Derivations"

Yes. Are you trying to make a point with it?

Go bring yourself up to speed and feel free to "weigh" in if you like https://en.wikipedia.org/wiki/Weight

I am up to speed, far more so than you.

Post your weight in kg and show the formula you used to arrive at that number and i will show you where g is.

That is physically impossible, akin to asking someone to show the volume of a container in amps.

It makes no sense.

kg are a unit to measure mass. Weight is measured in newtons (or kgweight if you like).

Yes, my weight in N will depend on G, but my mass in kg does not.

Answer a simple time puzzle 1kg brick will fall 100ft in how many seconds ? show your calcs

Yes, the time taken for an object to fall will depend on gravity. So what?

That doesn't refute anything I said.

I never said nothing is based upon gravity.

All I did was point out that you were wrong, kg doesn't depend on gravity, nor does density.

from wiki -

The distinction between mass and weight is unimportant for many practical purposes because the strength of gravity does not vary too much on the surface of the Earth. In a uniform gravitational field, the gravitational force exerted on an object (its weight) is directly proportional to its mass.

Yes, for practical purposes, weight can be expressed in kg, but that is not actually using the SI unit.

That does not make kg based upon gravity.

It does not mean mass is based upon gravity.

mass -weight both related to gravity dress it up how you like

The relation between mass and gravity is that the strength of gravity is proportional to mass.

But mass does not require gravity.

You can lie about it as much as you want, it won't make it true.

WIKI -- https://en.wikipedia.org/wiki/Density

The density, or more precisely, the volumetric MASS density

Yes. Notice the key word?

MASS

Not weight, mass.

Density is mass per unit volume, not weight per unit volume.

WIKI -- https://en.wikipedia.org/wiki/Buoyancy

If the object is either less dense than the liquid or is shaped appropriately (as in a boat), the force can keep the object afloat. This can occur only in a reference frame which either has a gravitational field or is accelerating due to a force other than gravity defining a "downward" direction (that is, a non-inertial reference frame). In a situation of fluid statics, the net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body.

Yes, buoyancy is based upon density and some other real or apparent force. I never said it wasn't.

But notice how even now it isn't actually dependent upon gravity and instead is just dependent on some real or apparent force that is proportional to mass.

In this case not even weight is necessarily based upon gravity. It is based upon whatever real or apparent force is acting.

Considering you seem so intent on calcs, perhaps you can answer this and show me exactly where gravity shows up:

I have a fluid. I inject it into a u-tube with a volume of roughly 0.1 ml.

This filled u-tube has an oscillation period of 0.036 seconds, and the relevant constants are 1000 g/(ml s^2) and 0.1 g/ml.

What is the density of this fluid?

What is the mass of this fluid?
