    Hi,
    I want to measure and mark the 50l level in my container for mixing salt water.
    So i started with a 1l container measuring up a 5l container wich in turn I will use to fill the 50l.
    I then wanted to check if the 1l container is actually = 1l.
    so i used 3 different 1l containers we have in the house and none of them measured the same.
    I then used the 1l tupper to fill a 2l tupper and this at least work, then decided to weigh the 2l and it was 1950g.
    So:
    does 1l water weigh 1kg or not?
    how to know which 1l container is actually = 1l?

    according to numerous hits in google 1l water = 1kg, seems my scale is out, will check with a calibrated weight from work, if this is true it means tupper's jug is wrong:confused1:
