What's the quickest way to work out what 4 hectares is in square light years?

Or 20 mph in Angstroms/epoch?

Ok, good thing i found my calculator...

1 lightyear^2 = (300,000,000 m/s times 365.25*24*3600 s)^2 = (9.47 * 10^15)^2 m^2 = 8.96 * 10^31 m^2

4 hectares = 40,000 m^2

40,000 / 8.96 * 10^31 = 4.46 * 10 ^ -28 square lightyears

Correct answer - but there is a somewhat quicker way to it....🙂

Well, Dan, me lad... It should... nay, must... start with a pint of some really good ale. Not the weak stuff mind you. Really good stout. Draw a diagram in the dust at your feet.... Fergot to mention, that you must be standing in an agreeable pub... with floors that have been used a bit, if you get the drift. With yer right toe, draw a diagram of the problem... stare at it for a while. Order another round for the boys, and get them involved. Make sure they don't walk on your diagram or you'll have to start over. At the end of the evening, you will surely have an answer that is agreeable to all. Even the bar maid if you tip with a bit of skill.😉 Let me know if this doesn't work, and i'll take it to the pub and work on it over the next year or two. Or until they turn out the lights.😵 Ahem... I just did a pint... and a preliminary estimate... i get like "point diddly squat to the minus 591st power..." I'll keep on it though... this is only an estimate.

I like your approach! Please note I said quickest and not longest or most fun but, by all means, carry on! 🙂🙂🙂

Well, the method I have in mind is not so good for that (how long is an epoch?), but as a guide it should take most people here about 30 seconds or less to find out what 3 light years cubed is in US cups if they use my approach.

That's a lot quicker than my method. Mine is just wait till somebody gives the answer 😉

Maybe its a bit of an unfair puzzle. I'll post the answer on Wednesday if nobody has got it.

Good strategy, and when someone gives the right answer: That's what I ment!!!😀

Here the answer as promised, remove the line returns (to defeat the pesky [WORD TOO LONG]) in the link:

http://www.google.com/search?

&oe=UTF-8
&q=four+hectares+
in+square+light+years
&btnG=Google+Search

By the way, anyone know any better ways to suppress word too long or to get hyperlinks to work in posts?

You could send a feedback and ask if they want to make it posible to make hyperlinks

use www.tinyurl.com to shorten long url's

the answer is at: http://tinyurl.com/qj1q

oh BTW my "tinyurl" link is now the shortest answer!!!

Yea that's right make me a sammich! 😀
