Encalc – Powerful Online Scientific Calculator

With students going back to class this month, a new online scientific calculator has launched to help with all of your E=mc² needs. Earlier this summer we reviewed an excellent online calculator named eCalc. Encalc is as scientific as you can get. The company describes the calculator as, "Its strength lies in its ability handle units and dimensional analysis, to define variables and its large database of constants. Parenthesis and scientific formulas are also supported."

The entry box can understand real language questions — e.g. "2 cm + 3 meters expressed in feet". There’s a tape of all of your computations for easy reference and if you click a computation it brings it back to edit.

Encalc is a great example of a Web tool that needs an embed option for students and teachers. When your computation is completed, you may want to share it with notes.
