About AyeCalc

What AyeCalc is for

The site focuses on useful tasks people need to complete: converting units, checking design values, estimating quantities, and understanding the method behind an answer. Tools are intended to work quickly without requiring an account.

AyeCalc covers practical image editing, CSS and frontend development, unit conversion, and loan-payment estimates. New pages should add a distinct practical capability rather than exist only as a keyword variation.

Product principles

Correctness and clarity come before traffic or monetization. Every substantial tool should show its assumptions, units, formula or transformation rule, rounding behavior, limitations, and an example where that context helps.

• Keep calculations local to the browser when a network request is unnecessary.
• Use primary or authoritative references for standards and fixed conversion factors.
• Design for keyboard access, readable contrast, responsive layouts, and stable results.
• Avoid fabricated ratings, usage claims, credentials, testimonials, and artificial urgency.

What the tools can and cannot do

A calculator applies its documented inputs and rules. It cannot infer missing real-world context, measurement uncertainty, local regulations, professional judgment, or project-specific requirements that were not supplied.

Results should be independently reviewed when they affect financial, medical, tax, legal, safety, or other consequential decisions. AyeCalc provides informational utilities rather than professional advice.

How the site improves

Pages are reviewed when formulas, technical standards, product behavior, or supporting guidance changes. Visible review dates describe content review; they are not automatically refreshed on every deployment.
