Convert paper weight between GSM (metric), US basis weight in pounds (bond, offset, book, text, cover, bristol, index, tag, newsprint), and ounces per square yard. Deterministic, offline, zero cost. Handles the US-basis-weight trap where 20 lb bond is not the same paper as 20 lb cover.

Paper reference toolkit for OpenClaw. Three deterministic tools: weight conversion (GSM, US basis weight, oz per sq yd); paper size lookup for 44 formats including ISO A/B/C, SRA, RA, US Letter/Legal/Tabloid, ANSI, ARCH, JIS B; and grade summary for 25 common paper grades (kraftliner, testliner, SBS, FBB, LWC, and more). Offline, no API, no config.
