Conversion Kit

Offline unit converter

Free · Designed for iPad. Not verified for macOS.

Conversion Kit turns your iPhone into a fast, reliable unit converter that works entirely offline. Every conversion runs on data bundled inside the app. No internet connection, no account, no ads, and nothing about your usage ever leaves your device. WHAT YOU CAN CONVERT 43 categories and 207 units, including: • Everyday — length, mass, area, volume, time, speed, temperature, digital storage • Engineering — pressure, energy, power, force, torque, density, flow rate, acceleration, frequency, angle • Electrical — current, voltage, resistance, capacitance, charge, magnetic field, conductivity • Science — amount of substance, molar concentration, molar mass, viscosity, radioactivity, radiation dose, pH, decibel • Astronomy — astronomical distance and mass • Clinical reference — glucose, total cholesterol, creatinine, urea, bilirubin, hemoglobin, drug dosage FEATURES • Instant results as you type • Search across unit names, symbols, and aliases • Favorites for the pairs you use most • History you can browse, reopen, or switch off entirely • Light and dark themes • English and Vietnamese • Accessibility support for VoiceOver and larger text BUILT FOR ACCURACY Conversion Kit uses decimal arithmetic instead of floating point, so results stay exact where they should be. Categories that need care, such as clinical analytes and drug dosage, show a warning before you convert, because those conversions depend on context like molar mass. PRIVACY No data collection. No analytics. No advertising. No account. Your history and favorites stay in the app's private storage on your device and are removed when you delete the app. NOTE Clinical unit conversions are provided for reference and educational purposes only. Conversion Kit is not a medical device and does not provide medical advice, diagnosis, or treatment. Always confirm values against your own clinical references and professional judgement.
