I have a large weight of 40 Kgs. But I have to weigh 7 Kgs.?

My friend told me that I should break that weight into four parts of differents weights so that I can weigh any denomination of weight 1 Kg to 40 Kg i.e. 1Kg, 2Kg, 3Kg.........39Kg and 40 Kg using them. What should be the weights of four small weights?
