Free Scientific Calculator
A full scientific calculator in your browser, covering everything from basic arithmetic to trigonometry, logarithms, exponents, statistics, matrices and unit conversion — switchable between modes without leaving the page. Type an expression or use the on-screen keypad, and results calculate instantly.
Multiple modes are available from the same tool: basic, scientific, graphing, programmer, statistics, matrix, converter, equation, complex and finance — so whether you need a quick square root or a matrix determinant, it's all in one place.
Key features
Multiple calculator modes
Switch between basic, scientific, programmer, statistics, matrix and more from one interface.
Full function set
Trigonometry, logarithms, exponents, roots, factorials and constants like π and e.
Keeps a history
Review and reuse previous calculations without retyping them.
Works on any device
Full keypad on desktop, touch-friendly layout on mobile.
How to use it
- Choose the calculator mode you need (scientific, programmer, statistics, etc).
- Type an expression or tap the on-screen keys.
- Press equals or let it evaluate live to see your result.
- Check your calculation history to reuse previous results.
Worked example
Example
In scientific mode, entering sin(45) with degree mode selected returns approximately 0.7071, and log(1000) returns 3.
Who uses this tool
Students
Handle trigonometry, algebra and statistics homework in one tool instead of switching apps.
Engineers and professionals
Quick access to scientific functions, matrix operations and unit conversions.
Anyone needing more than basic arithmetic
Square roots, powers, logs and trig functions without a physical calculator.
Tips for the best results
- Check whether you're in degree or radian mode before running trigonometric functions — a wrong mode gives a wildly different answer.
- Use the history panel to chain calculations without re-entering previous results by hand.
- Switch to matrix mode for linear algebra instead of manually multiplying matrices term by term.
- The programmer mode is useful for quick binary, octal and hexadecimal conversions without a separate tool.
Common mistakes to avoid
- Leaving the calculator in radian mode while expecting degree-based trig results, or vice versa.
- Forgetting order of operations when typing a long expression — use parentheses to be explicit.
- Using basic mode for something that needs scientific or matrix mode, and getting an incomplete result.
