TTRPG Unit Conversion Cheat Sheet (to the metric measurement system)

Tabletop roleplaying games (TTRPGs) originating in the U.S. do not typically use the metric system for measurement, leading many players and GMs to struggle at first to visualise and understand units of measurement in-game. Whether using theater-of-the-mind or miniature-based play, this cheat sheet will hopefully help such players and GMs navigate the worlds in which they adventure. We include conversions for measurement units of distance (length, height, and width), weight, area, volume, and temperature, as well as melting points for several materials common in many TTRPGs.
