How much does the Earth weigh in regards to what? Weight is a force and as Newton so apply pointed out F=Ma. If we looked at how much the Earth weighed in regards to the sun, then you could figure out the gravitational attraction of the two masses and apply the Universal Gravitational formula to figure out the Earth's weight. Why you would want to do this is beyond me. I think what you want to know is how much mass the earth contains, either in kilograms or (in the archaic English System) in slugs.

Approximately 5.97 x 10^24 kg.
This is so huge that in comparison, every human being combined (6 billion of us, each about 150 lbs) make up about .000000000007% of the earth. Add in a million tons of stuff for each and every person and that still only amounts to .0002% of the earth. So really, people and our stuff are an insignificant part of the whole earth.
Finding the mass of the Earth or any other celestial body is done using Newton's Law of Universal Gravitation. Basically, the rate an object accelerates due to gravity, along with the radius of the planet, tells you the mass of the planet.

Geez, another dumb question!!! The word is 'weigh'. Until you get your grammar right side up, the relative 'weight' of our planet, even if you're given the answer, is a moot point. Obviously you need an education that includes 'an education'. Until then, stick to the basics. Your question is out of order because your brain has not advanced enough to be able to correctly spell your question. This is the rout to your inability to even approach the answer to your question with any ability to understand it in the first place!!! Why are you young people so inept at learning in this age. I'm 62 yrs old(geezer), but my peers forgot more than you will ever learn. Get to the library - get a book or two. Lazy - lazy - lazy!! Sorry - did I wake you up!!! Hopeless!!!

The earth is weightless. It is in orbit around the sun, so it is said to be in free fall. An object that is falling according to the laws of gravity is weightless, so the earth, despite it's great mass, has no weight.

The Earth, itself, is weightless, it has to be as it's floating in space where there is little or no gravity. However, you could weigh it on the sun or other large massive stellar or planetary bodies.

Oh yes, like we have weighed the earth so we know, right?
