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.

How it’s made

Sawdust Math is an independent project, not a content farm. Every calculator here starts from published formulas and reference data, and gets checked against independent hand calculations before it ships. When a reader reports a discrepancy, we re-derive the math and publish the fix.

Corrections

If a result here disagrees with your build or your reference book, we want to know. Write to us via the contact page — corrections ship fast.
