Frequently asked questions
Are EngineerMint's calculators free to use?+
Yes. Every tool on this page is free, runs entirely in your browser, and never stores your inputs. No login required.
Can I use these calculators for permitted construction?+
No. These tools are for early sizing, sanity checks, and education. Any drawing submitted for permit must be sealed by a licensed Professional Engineer in the project's state.
Which engineering disciplines are covered?+
Civil, structural, mechanical (HVAC and piping), electrical, and quantity-takeoff tools — plus career tools like a salary calculator and resume builder tailored to engineers.
Do you support metric (SI) units?+
Yes. Most tools accept either US customary or SI inputs and output both side-by-side so you can hand results to international collaborators.
Will more tools be added?+
Yes — load combinations, foundation sizing, conduit fill, duct sizing, and a soil-bearing checker are next. Email tools@engineermint.com if there is a calculator you wish existed.
