Wombat – scientific calculator with physical units

Wombat is a high-precision scientific calculator for Linux that uses Numbat for mathematical expression evaluation. It combines scientific calculations with support for physical units, making it particularly useful for engineering, science and technical work.

The application maintains a persistent interpreter session. Variables, user-defined functions and imported modules remain available between calculations, allowing related expressions to be evaluated without repeatedly entering the same definitions.

Wombat can work with quantities that include physical units. Dimensional analysis helps identify incompatible operations, while unit conversion makes it possible to express quantities in different measurement systems.

The interface includes a scrollable history with syntax highlighting, helping users review previous expressions and results. Automatic completion offers suggestions for functions, variables, units and constants as expressions are entered.

Wombat also provides browsers for mathematical functions, physical constants and measurement units. These can be used to insert expressions without remembering their exact names. Its responsive interface accommodates desktop and touchscreen devices running Linux.

This is free and open source software.
