SpeedCrunch is a light weight, fast, precision scientific calculator released under GPL.

SpeedCrunch is a light weight, fast, precision scientific calculator released under GPL. The first time I ran this calculator on my machine, I found its interface rather queer; considering I was used to the traditional view of a calculator.

SpeedCrunch has a large text area (Output) which displays the result of the calculation and a small text field (Input) right below it in which the user can type commands. Talking of commands, there are a whole lot of stock commands available.

Uses of SpeedCrunch calculator.

You can use SpeedCrunch to calculate complex quadratic equations, find the surface area of 3D and 2D objects, use inbuilt commands by typing them in the input instead of using the mouse and much more.

There are around 45 constants built into SpeedCrunch which can be used in your calculations readily with the click of a mouse. Some examples of these constants are Avogadro’s number, Atomic mass unit, Coulomb’s constant, Earth mass, Light year, Elementary charge and so on. You can view the full list of constants by using the keyboard shortcut [Ctrl+2]. To use the value of the mathematical constant Pi, just use ‘pi’.
