About this tool: Scientific Calculator
A browser-based scientific calculator with a parser that handles arithmetic, parentheses, powers, square roots, trigonometry, logarithms, constants and factorials without using JavaScript eval().
Use it to compare scenarios quickly while keeping the relevant values, units, dates or rates visible on one page.
Scientific Calculator is presented in the shared NexterHub tool layout so the working controls stay near the top while the method, example, limitations and related utilities remain available below the result.
How it works
The calculator tokenizes the expression and evaluates it with an operator-precedence parser; it does not use JavaScript eval().
Practical example
sin(30)^2 + cos(30)^2 in degree mode returns 1.
Important notes
Check the entered units, dates, decimal placement and any assumptions before relying on the result.
Privacy & processing
The calculation is performed in the browser from the values you enter.
