About ShipCalculators.com

ShipCalculators.com is a continuously expanding library of maritime calculators and long-form encyclopedia articles. Every calculator shows the formula it implements, traced back to its exact MEPC resolution, EU article, or class-society circular. No login, no tracking beyond aggregate analytics, no data leaving the browser.

How we work

Every formula is regulation-cited

      Each calculator on the site shows its formula in plain text, with the symbol legend and the regulatory source right alongside the result: IMO MEPC resolution, EU MRV/ETS article, MARPOL Annex VI provision, or class-society notation document. Nothing hidden behind a black box.
