FAQ

Is this really offline?

Yes. After a page loads once, your browser can reuse it without a connection. For the newest version, refresh when you’re back online.

Where do the formulas come from?

We use widely accepted ag math and unit conversions. Each calculator lists its equations and assumptions directly on the page.

How precise are the results?

We round to practical increments and show units (e.g., acres, gallons, bushels). Real-world factors like moisture, slope, implement wear, and soil type can affect outcomes—treat results as estimates.

Can I suggest a new calculator?

Yes. Send ideas to [email protected]. We prioritize tools that save time in the field.

Why might I not see ads?

Ads only load if you choose “Allow ads” in the footer’s Privacy choices or in the consent banner. You’ll still get full functionality without ads.
