Online Scientific Calculator
This free scientific calculator supports all the functions you'd find on a physical scientific calculator, right in your browser. Perform basic arithmetic, trigonometric calculations, logarithms, exponents, and more.
Available Functions
- Basic: Addition, subtraction, multiplication, division, percentage
- Trigonometry: sin, cos, tan and their inverses (with degree/radian modes)
- Logarithms: Common log (base 10) and natural log (base e)
- Powers: Square, cube, arbitrary exponents (x^y), square root
- Other: Factorial, absolute value, reciprocal, constants (π, e)
- Memory: Store, recall, add to, and subtract from memory
Degrees vs Radians
Toggle between degree and radian mode using the DEG/RAD button on the display. In degree mode, trigonometric functions interpret input as degrees (e.g., sin(90) = 1). In radian mode, input is in radians (e.g., sin(π/2) = 1).
