Editorial Policy
Show the method
Every calculator includes the equation, units, assumptions, and a worked example. A result is an estimate within that stated model, not a measurement of a particular vehicle.
Check the math
Our launch checks cover known examples, zero and invalid inputs, conversion consistency, and relevant boundaries. Automatic checks confirm mathematical behavior; they do not establish vehicle compatibility or professional automotive expertise.
Use sources carefully
We prefer government agencies, standards organizations, and manufacturer documentation for factual automotive guidance. A source link identifies related guidance; it is not an endorsement. Geometry-based tools show their derivations directly.
Be honest about authorship
Content and software were prepared with AI assistance. No independent automotive professional has reviewed the launch pages. We will name reviewers and state relevant credentials only after a real review has taken place.
Keep examples distinct from facts
Default fuel prices, electricity rates, efficiency assumptions, and vehicle dimensions are illustrative. We do not present them as current prices or specifications for a named vehicle.
Corrections and updates
When a calculation changes, we test the revised behavior and update the page date. To document a suspected error, use Share result to capture the inputs and retain the expected result and its source. A public corrections contact is not yet available.
Commercial independence
The launch site has no advertising, paid recommendations, or affiliate links. Any future sponsorship or affiliate relationship will be labeled.
