The force of gravity is a function of mass divided by the radius squared.

Earth's radius is 3x that of the Moon (actually a bit more). Gravity from a spherical object is inversely proportional to square of distance from centre of mass, so this means Earth's gravity is 9x weaker (actually even a bit weaker) than it would be if Earth was as small as the Moon but had the same mass. This would mean that the Moon would have 1/9 the surface gravity of Earth, but remember that the radius ratio is actually even more than 3:1 since the Moon is denser I guess so that's where you get the 1/6.

Was never taught this in high school and I didn’t know the earth weighed so much compared to the moon until recently you snarky faggot. Figured it would be around 1/6 it’s weight.

According to Nutun it's
F= G m M / R^2
Now you are the small mass 'm'. Yes I know you are fat but you are still small compared to big M. So at a distance R from big M you will accelerate
a = F / m
a = G M / R^2

The moon's R is about 0.27 that of Earth's and similarly the M's about 0.012.

Now let's examine your claims.
You say the earth weighs 81 times as much as the moon.
Weight as we know is force. On Earth's surface, the moon would weigh 0.012a.

Now consider the following: ...

...the moon is not on Earth's surface!

First two guys explained it better. Also it’s hilarious to see a redditard of all people making fat jokes.

Does the radius of the planet have anything to do or just mass? Is there really observed examples of very small very massive objects having large gravity effects for their size (but apropos for their mass, as is thought and expected, just wondering if there is verified evidence)

Both, same mass but higher density (so smaller diameter) will lead to a higher local gravitational potential

the moon is hollow so all the mass is concentrated in a thin shell, this focuses the gravity

if the distance from the center of the body is the kept the same then the gravity of the earth is 81 times that of the moon's.

Shouldn't it be 64x? Since it's 4x the diameter of the Moon

Nope, the force of gravity is given by a system of second order pdes

The surface of the Earth is further from the center of Earth’s mass. The effect of gravity weakens over distance

Is it correct to say the pressure at the center of the earth is the highest, but due to cancelling gravitational force from the surrounding mass its weightless, and that is how a solid inner core can spin/float in a molten outer core?

If I wanted to be pedantic I'd bring up that a planet doesn't "weigh" anything in isolation
