JY Tools is a small collection of focused science and engineering calculators built to make common lab, classroom, and reporting tasks faster to check.
These tools are intended for students, researchers, lab staff, and engineers who want a quick and readable way to verify routine calculations before using them in a notebook, report, protocol, or class submission.
The calculators on this site are designed to run locally in the browser whenever possible. They are meant to help with quick checks and workflow support, but critical decisions should still be reviewed against your official method, SOP, or instrument documentation.
If you spot a calculation issue, unclear wording, or broken link, you can contact the site owner by email:
