i got a Coir brick from Big W doesnt even make up to the right L’s

OK, I give in – what does “doesnt even make up to the right L’s” mean???

Liters.

How does that work?

I do believe the instructions indicate that you mix X amount of litres of water per Coir block and it should add up to X plus Coir = XC litres.

yeah i done what i was told 7l per Brick.

why isn’t it cubic metres? – litres is a liquid measure.

VG – bags of potting mix are 20 or 30 litres – so 7 litres would be a third or quarter of those.

A cubic metre = a tonne
A litre = a kilo..

Litres are used to measure cubic capacity of everything from plastic bags to the motor in your car.

A cubic metre = a tonne A litre = a kilo..

ok thanks – 1,000 litres in a cubic metre.

Clever. ;)

makes one wonder why we nnever used decimal system all along.

i could ask
- does a cubic metre of feathers weigh a tonne ?
- and if a kilo of lead is the size of an egg – where is your system then ?

but i won’t. i’m just please to know that’s there 50 bags of potting mix in a cubic metre.

Well I will tell you anyway

the weights mentioned relate to a volume of water, since it is a liquid and can easily fit any shaped space..

not feathers or lead which are solids and hard to squeeze into odd shaped molds..

i could ask
– does a cubic metre of feathers weigh a tonne ?
– and if a kilo of lead is the size of an egg – where is your system then ?

=======================

If you know the specific gravity of something, working out the weight of a known volume is pretty easy…

A fresh egg is slightly heavier than fresh water, it sinks. Let’s guess an egg has an SG of 1.3. That means it displaces 1/1.3 it’s weight in water.

One ml of water weighs 1 gram.

So a 60 gram egg displaces 1/1.3 × 60ml= 46.2ml.

Lead has an SG of 11.3.

So a lead egg the same size as a 60 grammer would weigh 522.06gms, or just under half a kilo… (46.2 × 11.3=522.05)

So without doing a displacement test of a 60grammer, the egg SG of 1.3 will have to do… 8^)

And a cubic metre of feathers doesn’t weigh a tonne. A tonne of feathers does though… ;^)

Depends if you compress a a tonne of feathers into a cubic metre .. which is more possible than expanding a tonne of lead to fit the same space.

A cubic metre = a tonne
A litre = a kilo..

Um No.

More correctly,
a cubic metre of fresh water = 1 tonne.
A litre of fresh water = 1 kilo.
(That’s at sea level.)

A cubic metre of concrete, for example, weighs 2.4 tonne.
Whereas a cubic of lead will weigh 11.3 tonne. (Crikey)

The standard for the metric weight system is the weight of fresh water .

VG, i’ve found the coir will swell further over night but seems to do so best when the water is a little warmer.
Measure your final volume in a 10 litre bucket. Easy to see what you’ve ended up with.
The coir blocks are great value i reckon.

Pfft. All over my head.
It’s good potting material and mulch thats what it is :)

Interestingly, a cubic of wet concrete and a cubic of set concrete, both weigh the same.
So the water doesn’t go anywhere, it just changes ‘form’ by chemical reaction with the cement. Cool innit!

i knew that lol. – i still can’t see litres of potting soil.

LOL. They’re sold by the litre. It’s just a measure. If you fill a 10l bucket with soil, it’s 10 litres of soil.
No hocus pocus there Pep!

yeah it says it makes 15Ls of the Coir.
