N2 - We perform a measurement of the Hubble constant, H 0, using the latest baryonic acoustic oscillation (BAO) measurements from galaxy surveys of 6dFGS, SDSS DR7 Main Galaxy Sample, BOSS DR12 sample, and eBOSS DR14 quasar sample, in the framework of a flat ΛCDM model. Based on the Kullback─Leibler divergence, we examine the consistency of H 0 values derived from various data sets. We find that our measurement is consistent with that derived from Planck and with the local measurement of H 0 using the Cepheids and type Ia supernovae. We perform forecasts on H 0 from future BAO measurements, and find that the uncertainty of H 0 determined by future BAO data alone, including complete eBOSS, DESI, and Euclid-like, is comparable with that from local measurements.
