I have an esky with internal dimensions ...... 900 mm long x 400 wide x 500 high.
How do I work out how many litres it holds apart from filling it with water for you smart arses out there :)
This has me totally stumped tonight !!!

180 litres ???


L .9m x W .4m X H .5m = .18m3

.18m3 = 180 l

180 is spot on. just multiply the dimensions and there you have it in cm3

Comes in really handy to know this. I have a cavity that I will be turning into a kill tank after measuring and finding out it was 100 litres..

Greg, did you allow for GST in that measurement?

A couple of things you need to factor in because i think it is about 178.5 litres;D
1. Do you have an evaporation blanket (pool cover) for your esky?
2. How much evaporation could have/may have/will occur during filling or emptying.
3. Are the dimensions you provided "exactly" correct?

Answer:
1. Evaporation blanket - not necessary by law for eskys, only for pools in drought conditions.
2. Who gives a sh#t.
3. Who gives a sh#t, don't really care.
;D ;D ;D

Mate, seriously, think the rest are on the mark, 180 litres.

Cheers

I work out litre volumes this way, easy to remember.

Convert the measurements to decimeters. 1 decimeter = 10 cm or 100mm

e.g The volume of 1 litre of water is 10cm x 10cm x 10cm. converted to decimeters is 1 x 1 x 1 = 1 (litre)

Your example is 900mm x 400mm x 500mm. Converted to decimeters is 9 x 4 x 5 = 180 (litres)

Spot on boys! Use the same way as greg said on the outside volume as the first step to finding out somethings buoyancy. eg. If outside dims were the same as that .9x.5x.4 =.18m3=180L= 180kg displacement. Take the weight of the container away say 5kg. Then the container will take 175kg sitting on it before it will sink to the water line (provided the container is sealed)

Sorry some superfolous (lol spelling) info for ya's. Maybe help someone out tho

Pete - no I didnt :o:o I also didnt factor in the bloody temperature as there is quite a bit a shrinkage going on in Narangba in the mornings ::)::)


PS - Did I say I hate winter :-[:-[::)

Bring back the EAC :'(:'(:'(:'(

Shrinkage in Naranba?????????????????????????????????:-/

Shouldn't that be mutation from the toxic nuclear waste dumping and fire droppings from the past??????????????? ;) I thought you'd have 3 shrinkages to worry about now since you mutated. Narangba is sort of like the simpsons and springfield isn';t it?:P ;D :P Just joking Greg....LMAO

Some extreme ways of getting measurement there... :-/

If you measure in metres: (useful for a marlin icebox) :D
(0.9 x 0.5 x 0.4) x 1000 = litres

If you measure in centimetres: (useful for a mackeral icebox) :)
(90 x 50 x 40) / 1000 = litres

If you measure in millimetres: (useful for anything caught in Moreton Bay icebox) :o
(900 x 500 x 400) / 1 000 000 = litres

If you measure in kilometres: (useful for a whale icebox) ;D

gee ... I gotta get to work :'(

yeah: length X width X height, then divide by 1000 gives you litres

Or working
Length in metres times Width in meters = Area of item times depth = volume
and ditto for water yield off a roof to fill the tank for motor flushing of fill a tank in a boat off a roof or tarp.

ie Area of roof in sq meters times mm of rain equals litres of water yield.

So 1 mm rain on a sq M of roof = 1 litre

Tin or colourbond gives close to 100% yield but concrete tiles don't as they have to be wet up first. In constant rain periods this is not an issue. (not sure when SEQ will be back to that though)
