Power Calculator is a graphical calculator application for Windows XP released as a PowerToy, which, unlike the built-in offering, does not evaluate every time an operator is entered. Rather, the entire expression must be entered for calculation. In the Numeric calculator mode, it presents a visual keypad, in all other modes the expression has to be typed in. A scrolling text area maintains a history of all calculations.

The application also supports functions, of any arity, which can later be reused. For example, a function can be set by cube(x) = x * x * x, and later it can be used in an expression like 5 + cube(4). The advanced view also shows a graph of functions, along with a list of all the saved functions. A flyout window provides the option of choosing either a Cartesian co-ordinate system or polar co-ordinates. It can also save a list of variables for use in expression.

Unit conversions of the following types are supported: length, mass, time, velocity, and temperature. For example, a function to convert 0 degrees Celsius to Fahrenheit would be 0[c->f].[1]
