How Much does a bag of 70 litres of Compost weigh in Kgs

GoodBottleOfWine

Can anyone inform me how much a bag of 70 litres of compost weighs in Kgs. I did not hink it is 1 for 1 but I could be incorrect I have a garden truck that takes a maximum weight of 80kg so does that mean it can only safely take on bag of compost that weighs 70 litres.

Alexa says a litre of water weighs 2,.2 lbs which is a kilo 
So looks like you are right 
70 litres weigh 7o kilo

It will depend on the compost, how wet it is etc, but I would expect 25 to 35 kg weight.  Any bag of compost I have picked up has weighed considerably less than an adult.

How odd , why didn’t you simply ask Alexa what a litre of soil or compost weighs? FYI 0.2 kg. So to answer 70 x 0.2= 14(kg) or in old money 30lb or 2.2 st.

You’re welcome

It depends how wet the compost has got in the bag or whether it contains john innes which is negligible.
To answer your question an average bag is about 18kg so you could put 4  bags on your truck easily. 80kg is just over 12 stone  the weight of an average person!

Depends where and for how long it has sat in the pile at the retail outlet. Then it depends on the composition, which is variable.

The loading limit of the truck would also probably include an element underestimation for safety in this litigious age.

I'm no expert but manual handling regulations means it's likely to be 25kg or less. Most people couldn't even move a 70kg bag of something let alone lift it onto a truck.

I think the 125l bags from B&Q weigh more than 25kg. Once upon a time they did 150l bags, but like chocolate bars, they've undergone a shrinking process.

I think you're right.  Amazon helpfully states weights for most items and there are 75kg bags of compost at 24kg.

It depends on what's in the compost: 50l of manure weighs a lot more than 50l of compost!  I get 50l compost bags regularly and can lift them.  It's definitely not 1:1 in weight.
