This note is intended to serve as a reference for conventions used in the literature on string compactifications, and how to move between them, collected in a single and easyto-find place, using type IIB as an illustrative example. We hope it may be useful to beginners in the field and busy experts. E.g. string constructions proposed to address the moduli stabilisation problem are generically in regions of parameter space at the boundaries of control, so that consistent use of 2π's and frame conventions can be pivotal when computing their potentially dangerous corrections.
