Description
CalcBadger is a growing set of free online calculators and unit converters. Every formula is unit-tested against a named authoritative source (state DOT specs, NIST, USPS), each calculator shows its formula and the worked steps, and every page cites where its constants come from. Any tool can be embedded on your own site with one line of HTML, with a small credit link at the bottom. No signup, no ads inside the tools.
