PROJECTCALC / OUR STANDARDS

Contact ProjectCalc

Found a calculation issue or have a useful tool suggestion? Send us the details. Clear examples help us make this toolbox more dependable.

Reporting a calculation issue

• The calculator name and exact input values, including units.
• The result shown and the answer you expected.
• A formula, product data sheet or other reference that explains the difference.
• Your browser and device if the issue concerns the interface.

You may include a shared calculation link. It contains the input values, so remove any information you do not want to send. Do not send payment details, passwords or confidential project documents.

Suggest a tool

Tell us what you calculate repeatedly, which measurements you start with and what you need to order or decide. We prioritize practical tasks that can be explained and tested well.

Response expectations

We review messages as capacity allows and cannot promise an immediate response. For project-specific structural decisions, product installation instructions or urgent site questions, contact the qualified professional or supplier responsible for that work.
