Materials Tools

Materials tools for thickness, weight, and density conversion across the trade-specific units that workshops actually use: leather measured in ounces and irons, sheet metal in gauge numbers, lumber in nominal versus actual dimensions, and the metric or imperial equivalents you need when a supplier publishes only one of them. The arithmetic is straightforward; the value is having the conversion table memorized for you and surfacing the project context (what an 8-ounce leather is suitable for, what gauge a particular gauge number really represents) alongside the raw number. The most common misconception is that a 2x4 is actually two inches by four inches; nominal lumber dimensions are quite different from the actual planed sizes, which is the kind of thing that wrecks a project measured from a parts list rather than from the wood in your hand. If you are new to the category, start with the thickness converters if you work with leather goods, and bookmark the rest as you encounter them. The category is intentionally small and is expected to grow as we add tools for fabric weight, paper grammage, metal gauge, and the other unit systems that have not been added yet. Send a request through the contact page if there is a conversion you keep running into that we have not built.
