Description
The KLOE experiment has provided precise measurements
of the branching ratio of the main neutral and charged kaon
decay modes, of the $K_L$ and the $K^{\pm}$ lifetimes,
and of the $K_L$ vector and scalar form factors.
We present a description of the above measurements and an
overall fit of all our data, with particular attention to correlations.
These data provide the basis for the determination of
the value of the CKM matrix element $V_{us}$ and a test of the
unitarity of the quark mixing matrix.
\noindent
In addition our first measurement of the charge asimmetry in $K_S$
semileptonic decays, $A_S$, gaves us the possibility to
contribute to the knowledge of $\Re(\varepsilon)$ and
testing the CPT symmetry through the Bell Steinberger relation.
