The Alpha Magnetic Spectrometer is a high energy particle physics experiment in space. It is taking data continuously since May 2011 on the International Space Station. During the first 5 years of data taking AMS collected 2.3 million boron and 8.3 million carbon nuclei, measuring the B/C cosmic rays flux ratio between 1.9 GV to 2.6 TV with an unprecedented accuracy. The B/C does not show any significant structure and is well described by a single power-law $R^{\Delta}$ with index $\Delta = -0.333 \pm 0.015$ above 65 GV, in good agreement with the asymptotic behaviour expected from cosmic rays diffusion based on Kolmogorov turbulence theory.
