About Setpoint Tools
Setpoint Tools is a set of 30 single-purpose calculators and reference lookups, spread across 13 fields of work. Each one answers exactly one question and does nothing else. No account, no upload, no trial, no dashboard. The full list is on the home page.
The fields are as far apart as they look: a biller checking whether an ICD-10 code is still valid, an electrician sizing a conduit, a paralegal counting a filing deadline under Rule 6(a), a potter converting a cone number to a firing temperature. What they have in common is that the answer is a specific number, a published source for it already exists, and getting at that source on a phone is worse than it needs to be.
Why it exists
Most trade and professional reference material online is either a scanned PDF you have to squint at, or an article that explains a formula without ever letting you use it. Both leave you doing arithmetic you should not have to do, usually somewhere inconvenient. These tools do the arithmetic, and then tell you what the answer assumes.
The second half is the point. A number with no stated assumptions is not a reference, it is a guess with a decimal point in it.
How the figures are sourced
There are two kinds of tool here, and they are held to different standards.
- Tools that read a published dataset name that dataset on the page. ICD-10 codes and their annual changes come from the NCHS and CMS releases. OSHA penalties come from three places, because OSHA splits the job: the statutory limits are 29 CFR 1903.15(d), the unadjusted amounts are the annual Adjustments to OSHA Civil Penalties memorandum, and the procedure that turns one into the other is the Field Operations Manual, OSHA Instruction CPL 02-00-164, chapter 6. Deadlines follow Rule 6(a) of the Federal Rules of Civil Procedure. Cone temperatures are the chart published by The Edward Orton Jr. Ceramic Foundation, with the Fahrenheit values exactly as published and the Celsius marked as converted rather than passed off as Orton's own.
- Tools that are pure arithmetic have no dataset to cite, so they show the working instead. Crosswind is a sine and a cosine. Aspect ratio is a greatest common divisor. Where calculators of this kind disagree with one another it is nearly always rounding or a convention rather than a fact, and the page says which one it took.
Nothing here ships a figure invented for the purpose. Where the authoritative number lives in a document you hold, such as an aircraft's POH or a manufacturer's data sheet, the tool asks you for it instead of guessing on your behalf.
How they are checked
The arithmetic lives in tested modules rather than inside the page, so each rule is exercised against known cases instead of eyeballed. Reference datasets are rebuilt from the published source and diffed against what is committed, so a table that has gone stale fails the test suite rather than shipping quietly.
Two habits do more work than the tests. Where a derivation and a published table disagree, the tool takes the conservative one: at 21 °C the ambient ampacity formula gives 1.14 for a 60 °C conductor where the NEC table allows 1.08, so below 30 °C the correction is clamped to 1.0 rather than handing out capacity the code does not grant. And where a tool could not evaluate something, that is a visible third state. "Could not be checked" is never rendered as "nothing failed".
If you find a figure that disagrees with the current published source, please tell me. Getting a reference tool wrong is worse than not having one, and corrections go in ahead of anything else.
Who makes it
One person, working independently, and reachable on the contact page. Corrections and "this tool should exist" both land in the same place and both get read.
Setpoint Tools is not affiliated with, endorsed by or connected to any of the bodies whose material it references, among them OSHA, CMS, the NCHS, the FAA, the NFPA, the IET and the Orton Foundation. Where a standard is not freely licensed, only the physical facts and formulas inside it are used, never its text or its tables.
The site is supported by advertising. There is no sponsored placement, no affiliate link and no paid inclusion: nobody has bought their way into a result, a ranking or a recommendation here, and there is nothing to buy.
What these tools do not do
They do not replace the published source, and none of them is professional advice. A cone converter is not a substitute for witness cones. A penalty calculator does not tell you what OSHA will actually issue. A deadline calculator does not know your judge's standing order or your local rules. A weight and balance figure is a planning number, not a dispatch decision.
Every tool carries a section on where its answer stops being reliable, and that section is not boilerplate. On most of these pages it is the most useful part.
Privacy, briefly
Every calculation runs in your browser. Files you open in the claim and remittance readers are parsed on your own machine and their contents are never sent anywhere, because there is no server here to send them to: the whole site is static files. The tools that search large code sets do fetch reference tables from this site, but only the table, never what you typed. Advertising and cookies are covered in full on the privacy page.
