Cloudy Calculator

Cloudy Calculator The beloved Cloudy Calculator Chrome extension is back — rebuilt from scratch to work entirely offline, with improved unit handling, better plural recognition, and fixes for mixed-unit arithmetic. This update preserves the original’s simplicity and power while modernizing its internals for accuracy and reliability. Whether you’re doing quick everyday calculations, converting obscure units, or running scientific computations or currency conversion, Cloudy Calculator delivers instant, accurate results with zero privacy trade-offs. ⸻ About this Update • Based on the original Cloudy Calculator, now fully offline • 100% pass rate on all 423 comprehensive tests from comprehensive_tests.html • Enhanced unit parsing: recognizes plurals and aliases (liters, lbs, meters, hours, etc.) • No dependency on online services for math or conversions • Runs locally — no data ever leaves your browser ⸻ Features • Mixed-unit math: 10 lb - 2 kg in g, 2 cups + 500 ml in liters • Unit conversions for length, area, volume, mass, time, speed • Temperature conversions: 32 F to C, 100 C to K • Number base conversions: binary, octal, hex, decimal • Math functions: sin, cos, log, sqrt, pow, factorial, • Constants: pi, e, c (speed of light), phi, • Plural & alias handling: litres, lbs, meters, minutes, • Currency conversions ⸻ Testing This version has been verified with the original 423-case comprehensive test suite, achieving a 100% success rate. Tests cover: • All supported units & aliases • Temperature & currency conversions • Mixed-unit arithmetic • Base number conversions • Math function evaluations • Constant resolution • Robust error handling for invalid inputs ⸻ Privacy • No tracking • No telemetry • No analytics • All calculations happen entirely in your browser • No user data is ever stored or transmitted ⸻ I typically aim to identify and fix issues within 24–48 hours while balancing school and other commitments. However, Google’s approval process can take 3–5 days and is outside my control. This is a free tool that I maintain in my own time, and I do my best to keep it reliable for everyone. If you prefer to use a different extension in the meantime, that’s completely understandable — you should use whatever works best for you. That said, I would ask you to keep in mind that reviews have a lasting impact, while bugs are usually temporary and already in the process of being fixed.
