What's the formula for converting cubic litres to feet or vice versa ?
I am too lazy to pull out my 25 year old math homework.
Thanks,

A liter volume assumes 1000 cc of water, since 1 ml @ 4C=1cc, so 1 cu.ft.=28.32 l. :)

Izzat right?

ft3 x 28.316 = L

I told you, it's been 25 years ! :dont-know

Zilch, possibly you show your age here :) Between 1901 and 1964 there was a rather bizarre definition involving the base mass unit and properties of water ("1 liter is the space occupied by 1 kg of pure water at the temperature of its maximum density (3.98 C) under a pressure of 1 atm."), see http://en.wikipedia.org/wiki/Litre. Prior to, and after this period, 1 liter equals 1 dm^3 by definition. Apart from that, cu.ft. and l (or L) are themselves "historical garbage", since of course neither of them are SI units.

After this hair splitting, here's how I "remember" the conversion factor:

1 ft = 12 in
1 in = 25.4 mm
1 m^3 = 1000 l

=>

(12 * 0.0254)^3 * 1000 = 28.317

Closing rant: BTW, 'deci' and 'centi' prefixes are also historical garbage, as the recommendation since long is to use 'milli' instead (e.g. m and mm is fine, but not dm or cm, and thus not dm^3 or cm^3 either).

Alas, the hour and the day are not SI units either, apparently.

I am doomed.... :p

I don't cube in my head.

And my 5th decimal place is forever uncalibrated....
