BMI Calculator
This calculates the BMI (Body Mass Index) of a typical adult given their height and weight. Approximately 18 to 23 is considered typical. A BMI above 23 is higher than normal. A BMI under 18 is lower than normal.
What is Encalc?
Encalc is an online scientific calculator. Its strength lies in its ability to handle units and dimensional analysis, to define variables, and its large database of constants. Parenthesis 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]])".
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.
integrate(sin(x))
integrate(sinh(x), 0, 2)
diff(cos(x))
simplify((x^2-1)/(x-1))
matrix([1, 2], [3, 4]) * matrix([x, 1], [-1, x])
matrix([x, 1], [-1, x])^2
