Unit Converter

A professional, floating engineering unit converter for Chrome.

Unit Converter Professional unit converter & electronics calculator. Convert text on any page, decode resistors & SMD components instantly. Description The Ultimate Swiss Army Knife for Engineers, Students, and Makers. Stop switching tabs to convert units or decode components. Unit Converter is a powerful, privacy-focused extension that brings professional engineering tools directly to your current webpage. Whether you're reading a datasheet, writing a lab report in Google Docs, or browsing component listings, accurate conversions are just a click away. Why Install This Extension? • Zero Context Switching: Convert values without leaving your work. • Smart Recognition: Select text like "4.7 kOhm" or "100 mph" on any website, and it just works. • Offline Mastery: 100% local operation. No internet required, no data collection. • Electronics Specialist: Includes advanced tools for Resistors and SMD components that standard converters lack. Key Features 1) Universal Unit Converter A comprehensive floating calculator supporting virtually every engineering unit: • Mechanical: Length, Mass, Force, Pressure, Torque, Speed, Area, Volume. • Electrical: Voltage, Current, Resistance, Power, Capacitance, Inductance, Frequency. • Physics & Data: Energy, Temperature, Time, Data Storage, Internet Speed Download Calculator. • Smart Input: Types 5k, 10M, or 4u? We understand standard engineering prefixes automatically. 2) Smart Text Selection (Magic Feature) Encounter a unit while browsing? • Highlight & Convert: Select text like "50 psi" or "120 km/h" on any webpage. • Instant Context Menu: Right-click to see the conversion immediately in the menu. • Platform Support: Works where others fail—including Google Docs, Word Online, and PDF viewers. Optimized for Google Docs: To enable real-time text modification within Google Docs, you must go to Tools > Accessibility and check all available options. Google Docs restricts external text manipulation by default; enabling these settings grants the extension the necessary permissions to interact with and update your document content directly. Word Online Support: When working in Word Online, simply select your text and convert. The result is automatically copied to your clipboard—just press Ctrl+V to paste it back into your document instantly. 3) Advanced Electronics Tools Resistor Color Code Calculator: • Forward: Select colors (4, 5, or 6 bands) to get the resistance. • Reverse Mode: Type a value (e.g., "4.7k") and see exactly which color bands you need. • Live Visuals: See a realistic rendering of the resistor component. SMD Code Decoder (New!): • Resistors: Decodes standard 3/4 digit codes, R-decimal formats (e.g., 4R7), and the complex EIA-96 standard (e.g., 01C). • Capacitors: Decodes standard markings (e.g., 104, 4n7) into readable pF/nF/µF values. 4) Privacy & Performance • 100% Local: No external API calls. Your data never leaves your browser. • Lightweight: Instant startup, minimal memory usage. • Clean Design: Modern, dark-mode compatible interface that feels like a native app. Perfect for: • Electrical Engineers: Quickly verify SMD codes and resistor values during PCB design. • Students: Check homework answers directly in your browser. • Makers & Hobbyists: Order the right parts ensuring 100% accuracy.
