Free Online Scientific Calculator
Use our free scientific calculator to solve mathematical calculations quickly and easily. Whether you are a student, teacher, engineer or simply need help with everyday calculations, this online calculator provides useful mathematical functions in one place.
Switch between Simple and Scientific modes depending on the calculation you need. The calculator works directly in your browser, so you don’t need to install any software.
Scientific Calculator Features
Our online scientific calculator includes a range of mathematical functions:
- Basic arithmetic: Addition, subtraction, multiplication and division.
- Trigonometry: Calculate sine (sin), cosine (cos) and tangent (tan), including inverse trigonometric functions.
- Logarithms: Work with common logarithms (log) and natural logarithms (ln).
- Powers and roots: Calculate exponents and square roots.
- Mathematical constants: Use important constants such as pi (π) and Euler’s number (e).
- Additional functions: Use parentheses, percentages, factorials and other supported operations.
How to Use the Scientific Calculator
- Select Scientific mode at the top of the calculator.
- Choose the mathematical function you need.
- Enter numbers and mathematical expressions using the buttons.
- Select the equals (=) button to calculate your result.
- Use the clear or delete button to start a new calculation or correct your expression.
For trigonometric calculations, check whether the calculator is set to Degrees (DEG) or Radians (RAD) before calculating.
Simple Calculator or Scientific Calculator?
The Simple mode is suitable for everyday calculations such as addition, subtraction, multiplication, division and percentages.
The Scientific mode provides additional mathematical functions, making it useful for more advanced calculations involving trigonometry, logarithms, powers and roots.
You can switch between both modes whenever you need.
