Feedback
If you are reporting a problem with a calculator, converter, checker, or file tool, include the tool name, the inputs you used, the result you saw, and what you expected instead. For formula or methodology corrections, links to primary references are especially helpful.
For new utility ideas, describe the task you are trying to finish and the result you would expect from a useful first version. utilkit favors focused tools that are easy to understand, easy to verify, and useful without account setup.
