Fxxk The Imperials

It is beyond simple unit conversion. Build compound conversions by combining units and currencies in ways other converters can't.

COMPOUND CONVERSIONS Convert complex units like USD per gallon to CNY per liter, or kg per cubic meter to pounds per cubic foot. Add multiple numerator and denominator units to build any conversion you need.

LIVE EXCHANGE RATES Daily-refreshed currency rates from the European Central Bank via frankfurter.app. Supports 31 currencies including USD, EUR, CNY, GBP, JPY, and more. Rates update automatically with configurable fetch intervals.

11 UNIT CATEGORIES Area, Currency, Data, Duration, Energy, Length, Mass, Pressure, Speed, Temperature, and Volume — covering 70+ units with full support for Apple's Measurement framework.

FAVORITES Save your most-used conversions for quick access. Each favorite has its own inline calculator — just type a value and see the result instantly, right from the Favorites tab.

SMART VALIDATION The compose mode checks dimensional compatibility in real time, showing exactly which dimensions don't match so you can fix your conversion formula on the spot.

SIMPLE & COMPOSE MODES Use Simple mode for quick single-unit conversions, or switch to Compose mode to build multi-dimensional conversions with an intuitive pill-based unit builder.

DESIGNED FOR iOS Built with SwiftUI. Supports Dark Mode, Dynamic Type, and VoiceOver.
