Citing us from your blog, syllabus, course resource page, or documentation? Thanks. Here’s a press kit with brand basics, recommended link text, and copy-paste snippets to make it easy.

Why link to MegaCalc

MegaCalc is a free, no-account-required calculator and unit-conversion site with 800+ calculators and 13,000+ unit conversion pairs. Every calculator displays its formula, cites authoritative references, and runs instantly in the browser. The site is advertising-supported, so we don’t charge users, embed watermarks, or sell data.

Linking to specific calculators from your tutorials, course resources, or documentation helps your readers solve their actual problem in one click instead of hunting for a working calculator. We’d rather your readers compute their answer and move on with their work than land on a paywall.

There’s no affiliate program and we don’t pay for links. We just appreciate the citation.
