Scientific Calculator: The Complete Guide
Type a full math expression and get the answer instantly. This scientific calculator handles powers and parentheses, the constants pi and e, and functions including sin, cos, tan, log, ln, sqrt, and more.
Who the Scientific Calculator is for
Students and professionals who need to evaluate scientific expressions without a physical calculator.
How to use the Scientific Calculator
- Type your values into the fields above — pick your currency or units where the calculator offers them.
- Results update automatically as you type; there's no submit button and nothing is sent to a server.
- Adjust any input to compare scenarios, then copy the result with a single click.
How it works
Enter an expression using + − * / ^ % and parentheses, with functions such as sin, cos, tan, ln, log, sqrt, cbrt, and exp, plus the constants pi and e. The calculator parses and evaluates it following standard operator precedence.
Features
- Trig, log & root functions
- Powers and parentheses
- Constants pi and e
- Instant evaluation
How to enter expressions
Write expressions the way you'd read them: 2^10 for powers, sqrt(2) for roots, sin(pi/6) for trig (angles in radians), and ln or log for natural and base-10 logarithms. Standard precedence applies — powers before multiplication, multiplication before addition — and parentheses override the order.
