    Question Kilograms to litres conversion

    I am having great problems trying to convert kilograms into cubic litres, please can someone help?
    I would like to know which is the best buy of a particular item (dried mealworms) but get totally confused with kgs and litres!

    I have no idea how to convert kgs to litres, so please could someone tell me which is the best buy:

    5KG dried mealworms @ 40

    or

    3 x 5.6 litres @ 40

    Any help greatly appreciated!

    TIA

    You can't convert them.
    Unless you know the density of the thing.
    Because kilogram is a unit of mass and liter is a unit of volume.
    Via the equation density = mass/volume you can find what you want(if you know the density).

    Hi ChessTal,

    Thanks for your reply.

    While browsing on a known auction site just now I came across this listing:

    '5KG dried mealworms (approx 30.8 litres)'

    Would you say that is correct?

    This means that they have packed 5 kg of dried worms into a space 30.8 litres big. You can use this information to find the density of dried worms. The desnity is 5/30.8= 0.162 kg/litre
    The second offer of 3 x 5.6 litres for 40 is 16.8 litres. We'll assume that they pack them as tightly as the 1 you found on the auction site. With the density figure we just calculated the weight is 16.8 x 0.162= 2.72 kg This is a lot lighter than the first offer so the first offer is a better deal.

    Hi Shakarri and thanks for your help.

    The second offer of 3 x 5.6 litres are actually packed in three plastic buckets.
    I'll go for the first offer of 5kg ... thank you so much.
