80kg
... well between 70 and 80kg
1 litre = 1/1000th of a cubic metre
1 cubic yard of compost = About 600-700 kg.
1 cubic metre = 0.7646 cubic yards
so 150 x ((600 x 0.7646) / 1000)

i wonder who the winner is? 
Right, does anyone know why it is measured by volume and not weight?
I thought it might be because the contents could be wetter one day and not the next so the weight would be too variable..?
And last question. B and Q have stopped selling farmyard manure, where else is it sold? Ive been down the stables rooting through a 50ft pile of hot stinky horse poo to get the well rotted stuff but its not rotted enough. Good for warming your feet up though

1m³ (10cm x 10cm x 10cm cube) is one litre and when this is water at 1G (normal earth gravity at sea level) this weighs 1kg. It's the whole basis of the metric system, tying weight and size together. However, the density of everything varies greatly, so for example, one cubic meter of plutonium weighs 19800 kg. Vice versa, NASA developed a solid material nick-named 'frozen smoke' which is 3 milligrams per cubic centimetre which is effectively 99.8% air. A bit like a McShake but less profitable

A 1dm cube is 10cm x 10cm x 10cm.
The mass of something is not affected by gravity... but it's weight is.

Oops, I did it again !
10x10x10cm is 1 litre which is 1kg (water @ 1G)
Got the 1m³ bit wrong. It is indeed 1000 litres, or 1000kg, or 1 metric tonne (water @ 1G).

CMs are made up, really there are only MMs and Metres.....
Not really on topic (but re. McDonalds); but did you know that there was more potato in a large milk shake than in their large fries?

The reason compost is sold by volume is because the weight of the packs changes based on water content. I sell logs by volume as well for the same reason, the weight changes drastically depending on where they have been stored, how long for and if it is raining on delivery day!

A litre is a measure of VOLUME.
A kilogramme is a measure of WEIGHT.
Simple.
A kilo is the size of a litre because, (here I quote wikipedia, not because its accurate as a whole but because it's the best plain language explanation)
A photo of THE standard Kilogramme.
The modern kilogramme is actually based on the weight of a litre of water at 4 deg C, Why? Buggered if I know, I suppose they had to chose a temperature because weight varies with temperature.
I've just realized, it's Friday night and I'm describing the difference between a kilo and litre on an internet forum... I HAVE NO LIFE

On 7 April 1795, the gram was decreed in France to be equal to “the absolute weight of a volume of water equal to the cube of the hundredth part of the meter, at the temperature of melting ice.” Since trade and commerce typically involve items significantly more massive than one gram, and since a mass standard made of water would be inconvenient and unstable, the regulation of commerce necessitated the manufacture of a practical realization of the water-based definition of mass. Accordingly, a provisional mass standard was made as a single-piece, metallic artefact one thousand times more massive than the gram—the kilogram.
