"Peggy LeMone, senior scientist at the National Center for Atmospheric Research in Boulder, Colorado, calculated the weight of a cloud. 'The water in [a little cumulus cloud] weighs about 550 tons," she calculates. While she compared the number to the weight of elephants, I prefer to bask in the knowledge that no matter how ungainly and heavy I may seem, I am lighter than the clouds." -- [livejournal.com profile] redaxe, referring to this.

Tis a cool quote but I'm confused about why a meteorologist weighing clouds would be news, and also why she is surprised by the results - this mainly because Forest's environmental science course was teaching him to do the self-same thing last week, and thats 2nd year university stuff...

weights n measures

One thing I like doing is using my metric knowledge to go where few choose to travel. For example one megagram (Mg) is equal to 1.1 english short tonne (or one metric ton) and since the aforementioned cloud was calculated at weighing 550 tonnes, it would weigh one half of one gigagram (Gg). I am guessing that people who actually would have a reason to use these measure are likely to lapse into scientific notation around this point. I also suspect that the 550 tonnes estimate was originally done in metric (and is a round number in it) and then converted to english.
