We explore the interplay between different definitions of
distortion for mappings f : X → R2, where X is any metric surface,
meaning that X is homeomorphic to a domain in R2 and has locally finite
2-dimensional Hausdorff measure. We establish that finite distortion in
terms of the familiar analytic definition always implies finite distortion
in terms of maximal and minimal stretchings along paths. The converse
holds for maps with locally integrable distortion. In particular, we prove
the equivalence of various notions of quasiconformality, implying a novel
uniformization result for metric surfaces.
