litres and kgs

[lizzydrippin]

Could someone tell me please how many kgs in a 30 litre sack of cat litter? Thanks..

[Buenchico]

Sorry, we can't.

Litres measure volume. (i.e. how much space is taken up).

Kilogrammes measure weight (or, more accurately, mass).

Without knowing the density of the cat litter (i.e. how much a certain volume of the litter weighs) it's impossible to answer your question.

Blimey Chris, you got me well flummuxed now! I always took it for granted up until now, that a kg was the same as a litre and it has always mystified that some things come in kgs and some in litres, even though they are both dried goods that are sold by the weight, for instance I buy cat biscuits in sacks of 15 kg but the cat litter comes in sacks of 30 litres (and for some reason I always thought that litres were for measuring the weight of liquids, milk etc). As for the density of the cat litter.....er well... I can only say that the 30litres of cat litter looks and feels very much like the sack of 15 kgs of cat biscuits! Heavy. Thanks for your help anyway x

I think a litre of water weighs 1 Kg. But that's no help to you here

[squarebear]

No, you might as well ask how many inches in a day. The two things are totally separate.

[johne1892]

How many inches in a day.....what made you think of that?

Freud would have a field day with you :o)

[lizzydrippin]

Ah, Thanks sandyroe, so my thinking that a litre equaled a kg wasn't complete pie in the sky then,...so a litre of water weighs a kg

[squarebear]

Yes but cat litter will weigh different. A litre of feathers will be much lighter than a litre of iron for example.

[wildwood]

A litre of iron? Oh dear!

A 30 litres bag of litter probably sounds like a better buy than 6kg or whatever.

[jomifl]

not if it is vermiculite

Some items are sold by weight, some by volume. Most annoying is one UK company that provides dried mealworms for bird food. They supply these in tubs containing 1000 millilitres, and in packs containing 1 kilogram. Such inconsistency is utterly frustrating. To work out the best value, you'd have buy both and use precision scales!

[lizzydrippin]

Thanks to everyone for your input, it's been an education for me!

This brand of cat litter http://www.purapet.co...nlight-cat-litter.htm has density 0.9 to 0.95gm/cc. So (as 1000 cc = 1 litre, and 1000 gm = 1 kg) 1 litre of this weighs 0.9 kg to 0.95 kg. 30 litre will weigh 27 to 28.5 kg. So the idea that 1 litre = 1 kg is not far out for this brand, it is rather denser than water.

[New Judge]

No it's not, jonathon, it's slightly less dense than water.

30 litres of pure water (at 4 degrees Celsius, if my memory serves me well) weighs 30kg - a bit more than the cat litter..

[JonnyBoy12]

Yes, I have a question for you. What does the colour blue taste like?

[DaisyNonna]

blue tastes cool and soothing

[Jonathan-Joe]

Judge, yes, I got it the wrong round! A silly mistake like, say, when someone cannot copy a sequence of letters accurately!

[giveup]

Why dont you stick to lbs and ounces etc. Weigh it on your bathroom scales and take it from there

[wildwood]

Jonathon. I suspect that your example of 0.9 to 0.99gm/cc is the maximum absorption range. I can't believe that fresh cat litter weights just a little bit less that water.

[DTCwordfan]

what a 'recital tit' of a subject this is especially when things get mixed up

[Jonathan-Joe]

I don't keep a cat so have no experience of litter. Perhaps I have misunderstood the "bulk density" figures given on the website. Here's another page of that site - http://www.valupets.c...-litter-assorted.html - which gives both weight and volume for packs. I'll let the OPer decide whether any are the type of litter thhey use.
