Contact us

We read every message. Whether you’ve spotted an error in a calculation, want a new tool, or have a business enquiry, here’s how to reach us.

What to include

• Bug reports: tell us which calculator, the numbers you entered, and what you expected vs. what you saw.
• Tool requests: describe the material or project and who it helps — we prioritize tools by demand.
• Corrections: if a bag yield or density looks off, send us the supplier spec and we’ll update it quickly.

How we handle your message
