How We Build Our Calculators
Every calculator on this site uses published formulas from textbooks, professional standards, or peer-reviewed sources. We use mathjs for safe formula evaluation, not eval(). No calculation runs on a server or sends your data anywhere.
Each calculator page includes the formula used, a step-by-step worked example, and answers to common questions. We test edge cases and document assumptions so you understand what the result means and when it might not apply.
