Scientific Calculator

Scientific Calculator evaluates mathematical expressions entirely in your browser — supporting trigonometric and inverse trigonometric functions in both degrees and radians, natural and base-10 logarithms, factorials, square roots, powers, mathematical constants (π and e), and grouped expressions with parentheses. A live result previews as you type, a 50-entry history log lets you reuse past calculations with one click, and four memory registers (MC, MR, M+, M−) let you store and accumulate intermediate values across multi-step problems. Built on the mathjs expression engine, it accepts the same syntax as most programming languages — making it ideal for developers, students, and engineers who want a keyboard-friendly tool that goes beyond a basic calculator without launching a full CAS system.

Simply input your data into the fields above. Our Scientific Calculator will process your information instantly. You can then copy the results or export them depending on the specific tool features like Live result preview as you type the expression or DEG and RAD angle mode toggle for all trig functions.
