About Sawdust Math

Every woodworker has the same bookmarks folder: a shelf-sag page that looks like it shipped with Windows 98, a segment calculator hosted on someone’s personal PHP page, and a forum thread from 2011 with the formula buried in reply #43. The math in those places is usually right — the experience is stuck in the past.

Sawdust Math rebuilds those tools properly: fast, mobile-friendly, free, and honest about where every formula comes from. Where a number has a source — the Forest Products Laboratory’s Wood Handbook, machining references, standards documents — we cite it. Where it’s a rule of thumb, we say that too.

Who makes this

Sawdust Math is built and maintained by bytesCaleb — a software developer who got tired of doing shop math on sites older than his tools. Every calculator here starts from published formulas and reference data, and gets checked against independent hand calculations before it ships. You can find me on GitHub.
