Scientific Calculator
Scientific — scientific Calculator evaluates the expression with scientific functions (trigonometric, logarithmic and powers), respecting operator precedence. This page runs that same calculation on your numbers, in your browser: no signup, no uploads, nothing stored.
Scientific Calculator turns your expression into the result using the standard method. The maths runs locally, so nothing you enter leaves the page.
About this calculator
Scientific Calculator evaluates the expression with scientific functions (trigonometric, logarithmic and powers), respecting operator precedence. That is the whole of the calculation — the mistakes happen in the inputs. It matters when you need the exact relationship checked quickly rather than worked through by hand. Worked example: Evaluate 2 + 3 × 4 using order of operations: 3 × 4 = 12, then 2 + 12 = 14 . Use the calculator with your own figures; it runs entirely on your device.
How to use
- Enter an expression, e.g. sqrt(16) + 2^3.
- Press Calculate to run the scientific calculator.
- Read the result: the value of the expression, with trigonometry in radians.
- Press Reset to clear the scientific calculator and start again.

FAQ
What functions are supported?
sqrt, cbrt, powers (^), logarithms (ln, log), and trigonometric functions, among others.
Do the trig functions use degrees or radians?
Trigonometric functions use radians. To convert degrees to radians, multiply by π/180.
Is it safe to use?
Yes — expressions are parsed and evaluated entirely in your browser without executing any external code.
Does the Scientific Calculator send my data to a server?
No — the Scientific Calculator runs entirely in your browser, so the numbers you enter never leave your device.
