Here you go, in case you've wondered what the actual km/s are when a ship moves at 485Gs:

To start with you typed km/s to G's. There is no such conversion. One is a velocity. The other is an acceleration. I believe you meant to type km/s^2. For neophytes that reads kilometers per second squared. Or as is written in the books, "KPS squared." May be where the confusion originated from.

For those wanting to convert G's to KPS just move the decimal place two spots to the left like everyone else as this approximation is close enough.

485G's ~= 4.85KPS

For the math neophyte it reads 485 is approximately equal to 4.85KPS. When hand written, the equals sign is double squiggled. But alas, double squiggled equals signs are not on a keyboard. Could be an alt number I suppose. If so, I have never seen it. In WORD, etc one can get this from the symbols drop box.

And THAT'S why I don't generally post on boards. Thanks for the kindly and yet incredibly condescending put-down. It's MOST appreciated when I was just trying to be considerate and helpful.

Let me leave you with this:
“All cruelty springs from weakness.”
―Lucius Annaeus Seneca
in De Vita Beata (On the Happy Life): cap. 3, line 4

What you say may not be cruelty in your mind, but may be the most ardent hateful torture in the mind of your listener. It is not up to the tortured to change the torturer; it is the place of the one torturing to effect change, for change may only come from within and not from without.

To start with there are SEVERAL math/physics neophytes on this board. Many have no clue what the ~ means if used in a document.

Do us the favor/courtesy of 5 seconds of proof reading next time. Our time is just as valuable as yours.

In fact it is more valuable as far more of us will spend far more of our time reading/responding to your fallacies than you would if you had bothered to proof read. :twisted:

If you consider a "neophyte's" posts unworthy of your time because they don't underatand the math or physics, don't read them and certainly don't reply.

One Gee = 10m/s/s

One Km/s/s = 100 Gees

My post clarified FOR the neophyte. Not because a neophyte is "unworthy". If someone is unworthy, I ain't replying. Haven't seen me replying to anything Skimper has posted in the last couple of months now have you?

Of course I am going to reply. No sense promulgating blatantly wrong information.

What was unworthy was the response when he got called on the carpet for not bothering to do a very simplistic proof read. Own up to your mistakes, take the blame/shame, and move on. Hopefully enough shame(Nothing wrong with a little nick to the ol' pride) was heaped, so one nudges their conscience causing a change in behavior. Proof Read.

Whining always gets a response/reply from me. Not a response the whineee in question will relish. Never let whining go without a response. It will only get worse as not responding reinforces this behavior. True in kids. True on the internet as well.

One G = 9.81m/s^2 isn't it?

10m/s^2 is a close enough approximation for reading the novels however.

In fact you could almost make an argument for the creation of a 'Metric G' to make the maths easier (if not precisely relevant to physics on Earth itself).

Saknussem, thank you for taking the time and making an effort to participate in the forums. As I'm sure Duckk will tell you, the forums are here for US neophytes to learn and as a community for Mr Weber's fans to socialise.

There is nothing wrong with lurking in the background, but it's always nice to have different input from different people, instead of just a relative handful of regular participants.

I'm no technophile myself, so I tend to make a lot of mistakes as well. My strengths lie elsewhere and I know it. So might yours, but who cares? They don't need to read your post or take the time to respond to it. Their choice to do so or not, so it's really stupid of them to get angry at you when they do.

Hah, you should go read my second-to-last post on the 'Technical Questions re Military Hardware' thread to see a really embarrassing example of just how technodumb someone can get, so don't pay attention to the Fly. He's generally just in a shitty mood, is all.

I assume that given the thousands of lanets with various surface gravities and that surface gravity varies with location on any planet, the Honorverse has evolved a "standard gee" of 10 meter/s/s exactly.

I know of very few applications where 10m/s/s is not sufficiently accurate. Very long range sniping is one of the few applications where two significant diggits is insufficient.

That would be logical, and I myself often use the 10 m/s^2 approximation and even once suggested that David might be doing the same. But someone pointed out that in the few cases where we get values in both gees and kps^2, it is clear that David really is using 9.81 m/s^2.
