KLOE has measured most decay branching ratios of K-S, K-L and K-+/--mesons. It has also measured the K-L and the K-+/- lifetime and determined the shape of the form factors involved in kaon semileptonic decays. We present in the following a description of the above measurements and a well organized compendium of all of our data, with particular attention to correlations. These data provide the basis for the determination of the CKM parameter vertical bar V-us vertical bar and a test of the unitarity of the quark flavor mixing matrix. We also test lepton universality and place bounds on new physics using measurements of vertical bar V-us vertical bar from K-l2 and K-l3 decays.
