Scientific Calculator
A scientific calculator with trigonometry, logarithms, roots, powers, and constants (π, e). Enter your values, click Calculate, and get the full result with its breakdown — everything is processed on your device, nothing is sent to a server.
All calculations run in your browser. Your data is never sent to our servers.
Example

About the Scientific Calculator
The Scientific Calculator extends the basic one with functions: sin/cos/tan (radians) plus sind/cosd/tand (degrees), asin/acos/atan, sinh/cosh/tanh, sqrt/cbrt, ln/log/log2, exp, abs, floor/ceil/round, and fact (factorial). Constants pi, e, tau, and phi are available.
Type an expression like "sin(pi/6) + sqrt(2)" and Calculate. Like the basic calculator, there is no eval — a dedicated parser only recognises safe math functions and operators.
FAQ
Is this Scientific Calculator accurate?
Yes. It uses standard formulas and runs directly in your browser at full JavaScript precision (plus BigInt/decimal.js for large numbers where needed).
Is my data sent to a server?
No. All calculations happen entirely on your device. No values are sent to or stored on our servers.
