Gene2memE has already posted arguing that the numbers in question are not accurate (while you could maybe get the first two by rounding, the last one seems completely wrong) and several rely on using a measurement system the majority of the world does not use. But we run into bigger problems in that this is a bad application of the Number of the Beast in Revelation. We see the same problem in your subsequent picture:
Again the claims are given with no citation whatsoever, and the numbers are of questionable accuracy (for example, it claims the force of gravity on Earth is 666 newtons. But a quick search indicates to me it is instead 9.8 newtons), and they also multiple times rely on relying on units that in some cases most of the world does not even use. Why do people simply see images that offer no sources and citations and then assume everything them is completely correct without performing some degree of verification first?
However, beyond the questions of the numbers in these images, we run into a larger issue, which is that they are not applying Revelation properly. While it does not explicitly state the number of the beast is the number of its name, Revelation 13:17 and Revelation 15:2 heavily favor that interpretation. Clearly, the numbers above do not come from any names. Additionally, Revelation 13:18 says, depending on translation, to be a man's number or man's number (the Greek word can be used to refer to either an individual man or mankind in general). But Earth revolution speed, tilt, curvature, and the rest are not those either.
But we run into a bigger problem than even that: The poorly researched meme images fall under the frustratingly common but still incorrect belief that the Number of the Beast is three 6's. It's not. It's six hundred and sixty six, the number. Revelation does not present the number of the Beast as three 6's, but rather the numerical value of six hundred and sixty six (it is therefore more accurate for translations to write out the number as six hundred sixty-six than 666). Heck, the Greek didn't even use our modern notation where you use the same symbol three times to write it out, they had the symbol for six hundred (χ), the separate symbol for sixty (ξ), and the separate symbol for six (ς). It was written as χξς (with a little line on top of it to show it was a number, the symbols in question were letters of the Greek alphabet, but when written with a line over them are used as numerals). This confirms to us that it's the specific numerical value of six hundred and sixty six that matters, not just finding three 6's together. So 66,600 or 0.666 or 66.6 don't mean anything; indeed, they're hundreds or even thousands away from the actual six hundred and sixty six value!
Revelation says the number six hundred and sixty six; not sixty-six thousand and six hundred, not six hundred sixty six thousandth, not sixty six and six tenths, not six times sixty times six hundred sixty six (which is actually 239,760, very far off!), not six hundred times six times six, and not one and six hundred sixty six thousandths. It says six hundred sixty six,
on the dot (a few manuscripts do offer 616, but of course if that is the number it throws out your entire claim anyway). Any number that is not exactly six hundred and sixty six is irrelevant. So even if those non-six hundred and sixty six numbers you blindly trusted without verification were correct--and at least some of them are clearly false--it still would mean nothing, because the number is six hundred and sixty six.
