Casinia

Casinia is an all-in-one utility app that includes a unit converter broad enough to handle the measurement situations you actually run into, from cooking to travel to engineering. All eight conversion categories, Length, Weight, Temperature, Volume, Area, Speed, Time, and Digital Storage, are built in, each with more than 10 individual units to choose from. Conversion happens instantly as you type: there is no separate "convert" button, just enter a value, pick your source and target units, and the result appears immediately. The calculator works alongside the converter for situations where you need both: switch to standard or scientific mode to run a formula, copy the result, and bring it straight into the converter without leaving the app. Casinia functions entirely offline and needs no account or login, every tool is ready to use immediately after install.
