🔬 Scientific Calculator
Trigonometry, logarithms, powers, roots, factorial, constants and memory.
About this tool
A full scientific calculator for the browser. It handles standard arithmetic plus trigonometric functions (sin, cos, tan and their inverses), logarithms (log, ln), powers and roots, factorial, π and e, and a memory register (MC/MR/M+/M−). Switch between degrees and radians for trig. You can also type expressions directly and use your keyboard.
Expressions are evaluated by a built-in math parser — no eval, no server calls. Everything runs locally and privately.
