The $\Lambda$CDM model successfully explains the majority of cosmologicalobservations. However, the $\Lambda$CDM model is challenged by Hubble tension,a remarkable difference of Hubble constant $H_0$ between measurements fromlocal probe and the prediction from Planck cosmic microwave backgroundobservations under $ \Lambda$CDM model. So one urgently needs new distanceindicators to test the Hubble tension. Fast radio bursts (FRBs) aremillisecond-duration pulses occurring at cosmological distances, which areattractive cosmological probes. However, there is a thorny problem that thedispersion measures (DMs) contributed by host galaxy and the inhomogeneities ofintergalactic medium cannot be exactly determined from observations. Previousworks assuming fixed values for them bring uncontrolled systematic error inanalysis. A reasonable approach is to handle them as probability distributionsextracted from cosmological simulations. Here we report a measurement of ${H_0}= 64.67^{+5.62}_{-4.66} {\rm \ km \ s^{-1} \ Mpc^{-1}}$ using fourteenlocalized FRBs, with an uncertainty of 8.7\% at 68.3 per cent confidence.Thanks to the high event rate of FRBs and localization capability of radiotelescopes (i.e., Australian Square Kilometre Array Pathfinder and Very LargeArray), future observations of a reasonably sized sample ($\sim$100 localizedFRBs) will provide a new way of measuring $H_0$ with a high precision($\sim$2.6\%) to test the Hubble tension.
