What UnitConvertr does

UnitConvertr (UnitConvertr.com, formerly unitconverters.net) is a privately operated, browser-based utility platform that provides free unit conversion and scientific calculation tools. It was launched in 2025 by Laszlo Bosak, an individual operator based in Hungary, and is not structured as a formal corporate entity. The platform serves students, professionals (engineers, architects, scientists), and everyday/hobbyist users who need to convert measurements across metric (SI), US Customary, and Imperial systems, or to perform trigonometric, logarithmic, and other scientific calculations.

The product surface comprises three web tools delivered at a single domain: a multi-category Unit Converter (Length, Temperature, Area, Volume, Mass, Time) built on the open-source convert-units library and rendered via an Angular front-end for responsive browser access; a Scientific Calculator supporting basic arithmetic, trigonometric functions in degrees or radians, exponents, logarithms, roots, and memory functions; and an add-on Hungarian-language Otthon Start Lakáshitel mortgage calculator for a specific 3% fixed-rate home loan program. There is no mobile app, no API, no SDK, and no third-party integrations documented.

The business model is product-led growth: users access the site directly without registration or payment, and revenue is generated solely through third-party advertising (Google AdSense), which uses cookies and web beacons for non-PII behavioral targeting. Go-to-market is entirely organic, relying on search engine discovery for high-volume conversion queries (e.g., "meters to feet", "kg to pounds") and Wikipedia-linked educational content about measurement systems, with no disclosed paid acquisition, sales motion, partnerships, or external funding.

Core offering

UnitConvertr operates a free web-based platform offering three interconnected tools: a multi-category unit converter covering Length, Temperature, Area, Volume, Mass, and Time across SI, US Customary, and Imperial systems; a scientific calculator with trigonometric, logarithmic, exponent, root, and memory functions; and a Hungarian-language mortgage calculator for the Otthon Start home loan program. All tools are accessible via unitconvertr.com without registration or software installation.

Product overview

UnitConvertr operates as a web-based utility platform comprising three interconnected tools: the core Unit Converter for transforming measurements across SI, US Customary, and Imperial systems; the Scientific Calculator for advanced mathematical computations; and the Otthon Start Lakáshitel Kalkulátor, a Hungarian mortgage calculator for the Otthon Start home loan program. All tools are accessible via the same web domain, with the calculator accessible as a toggle on the main converter page or as a standalone page.
