## What is Encalc?

Encalc is an online scientific calculator. Key features include the ability to handle units and dimensional analysis, to perform symbolic algebra and calculus, to define variables, and to lookup values from its large database of physical constants. Integration, differentiation, parentheses and scientific formulas are also supported.

## Unit Conversions

Encalc can be used for unit conversions and dimensional analysis. To convert from Metric to US Customary Units, try inputting "4 meters to feet" and hit "Calculate". Other conversions are handled similarly.

## Using Parentheses

Parentheses are necessary for many calculations. Encalc supports normal parentheses, e.g. "(2+3)/5". Square brackets are used for matrices and vectors, such as "dot([1,2,3], [-3,1,2])" or "matrix([[x,y],[1,-1]])".

## Handy Formulas

Encalc has a lot of formulas ready that you may find helpful.

## Defining Variables

Define your own variables to get the most out of Encalc. You can type "M" in the first box and "12 grams" in the second box to define "M=12 grams". From there, you only have to refer to M in your formulas.

## Physical Constants

Encalc has a database of hundreds of physical constants. "The speed of light" and "c" would both be equal to 299800000 m / s. Try other constants - there's a good chance it's in the database. To turn off the database, click Preferences. This is useful when you want to use a constant as a variable in algebra, e.g. "(a+b+c)^2" without using c = the speed of light.

## Calculus, Matrices, and More!

Encalc supports advanced mathematical functions.
