The strong ${K}^{\ensuremath{-}}p$ scattering length is extracted within chiral SU(3) unitary approaches from a very large variety of fits to low-energy ${K}^{\ensuremath{-}}p$ scattering data. Very good overall agreement with available scattering data is obtained and the resulting scattering length is compared with the new accurate kaonic hydrogen data from DEAR. The pole structures of the obtained fits to experiment are critically examined.
