Hi all, I just finished a NASA training session on the Rosetta mission. During the Q&A someone asked how gravity on the mission's target (Comet 67P) compares to Earth's. The answer was around 1/10,000. So if when I stand on a scale here on Earth it reads 63 kg, I *think* on 67P it would read 6.3 grams (about the same as a US 25 cent piece). Have I got that right? Wanting to make sure I've got the decimal in the right place. patrick
Kilo means thousand. so going from 63k to 63g only gets you part way there. You need to divide by 10 again. for the answer that is 1/10,000th. so you would weight 630 milligrams. DT

Thanks Daniel, Augh. I meant to say 63 kg. Being that that's 63,000 grams I divided that by 10,000 to come up with the 6.3 gram figure. I'm pretty sure I'd need to divide even further to get down in the milligram range. Thoughts? patrick On 25 Apr 2014, at 23:37, daniel turner <outwest112@yahoo.com> wrote:

My mistake! Sorry I'm but I need to catch up on sleep. But Patrick is bragging once again. This time about how little he weighs. 63k works out to 138 lbs. Does he wonder why he's booed at the club meetings. DT

It don't make a bit o sense with those dad-blame grams and kilograms and such -- talk Merican! If you 're gonna talk British, don't use our good old quarter as an example, use the dern British pound or somethin'. Oh wait you don't believe in pounds. Sent from Yahoo Mail on Android

Patrick, 6.3 grams or 6300 milligrams is what the scale would read on 67P - if it was a perfect scale that could register that close to zero - your Walmart bathroom scale would not qualify. Ed ------------------------ Quoting Wiggins Patrick <paw@getbeehive.net>:

You're welcome, Patrick, I certainly hope so! Too bad it was such a simple problem. It could have gotten interesting if you had wanted the scale reading in barley corns or some other ancient system. Ed -------------------------- Quoting Wiggins Patrick <paw@getbeehive.net>:
