It's hard to accurately convert M3 to weight but generally going on 1M3 is 2Tn then you will need a little over 3Tn.

i beg to differ squire
you cannot tell me that topsoil will be the same weight as ballast or MOT for a cubic metre? :)
i reckon topsoil depending on moisture to be about 1.4 t per cube
giving a total of 2.205 tonnes for this job
i would suck it and see and get 2 tonnes and see how far that goes
obviously moisture content will make a difference also the organic make up will affect the weight
remeber mark that the BM's bulk bags rarely weigh 1 tonne
mostly about .85 tonne
cheers fellas

Top soil is usually calculated as having a density of 1.45 T per m³ (see this bit ) so seeing as you have 1.6m³ you'll need around 2.3 tonnes. As LLL says, wet soil is denser than dry, but not by as much as you might think - remember, water has a density of 1T/m³, which is why soil sinks in water.

Lol, must have been "heavy clay" topsoil I was thinking of. Sorry about that. Sure theres never any harm in having a bit of extra topsoil, eh? :p

Topsoil is normally in bigger bags than aggregates (round here anyway) and you get one tonne 'moist'. It can then be either lighter or heavier depending on the weather.

half the people i know have .5 tonnes of sand/ballast/topsoil/bricks and various other bits and bobs from *mates* who ordered their stuff for them
i never guess ,just put it in a calculator and work it out,however squire its better to try and get it wrong once,than never try at all
:D
