About
Un1ts is a unit converter for the Mac, built natively with Swift and SwiftUI for the latest macOS features. Enter a value in a field and the app automatically converts it to all units within that category. Supported categories include Acceleration, Analysis, Angle, Area, Data, Density, Energy, Force, Illuminance, Length, Mass, Power, Pressure, Radiation, Radioactivity, Speed, Temperature, Time, Torque, and Volume.
Un1ts was first released in 2013 as an Objective-C app and was one of the developer's first Mac App Store releases. In 2019 the developer began a full rewrite in Swift and SwiftUI, and the current version is available exclusively on the Mac App Store as a one-time purchase. Recent updates have added British and American units for energy and power, water and mercury pressure units, and more data units. The app supports both Apple Silicon and Intel Macs.
Un1ts does not collect any user data; settings such as number style and significant digits are stored only on the user's computer.
