AllerCalc

AllerCalc is a lightweight Windows calculator whose purpose is to help you carry out expression calculations using various constants and functions, convert different units of measurements, as well as perform time-based payments using financial tools.

The application places on your screen the layout of a virtual calculator. You can enter data using the built-in buttons embedded in the calculator’s GUI or via keyboard input.

You are allowed to save the current worksheet to a file so you can easily import it in your future projects, and automatically save the worksheet with the performed calculations upon exit.

You may hide or show the keypad, make the main panel remain on top of other windows and adjust the number base (e.g. decimal, binary, octal), angle unit (e.g. radians, degrees), and number format (general or scientific).

AllerCalc comes with several tweaking parameters for changing the background color, modifying the font size and color of keypad, operator keys and function keys, running the program at Windows startup, and adding a new line after each calculation.

The calculator supports various types of functions, including algebraic, transcendental, trigonometric, hyperbolic, engineering, and statistical options.

There’s support for several conversion tasks, such as English to metric (e.g. acre to square meter, mile to kilometer, inch to centimeter, foot to meter, gallon to liter, ounce to gram) or vice versa (e.g. square meter to acre, meter to foot, centimeter to inch, kilogram to pound, meter to yard).

Financial tools help you perform calculations related to present and future values, annual interest rate, duration (in years), payment frequency, and date (end or begging of the period).

All things considered, AllerCalc comes with so many functions that it can easily replace your built-in Windows calculator, and is suitable especially for engineers and scientists.
