Scientific Calculator
Full-featured scientific calculator with trigonometric and logarithmic functions.
What is a Scientific Calculator?
A scientific calculator is one that goes beyond the four basic operations to include the functions you need for math, science, and engineering classes: trigonometric (sin, cos, tan and their inverses), logarithmic (log base 10, ln natural log), exponential (ex, xy), factorial (n!), the constants π and e, and parentheses with proper operator precedence (PEMDAS). Hewlett-Packard and Casio popularized the form factor in the 1970s, and today every smartphone ships one — but a browser-based version is convenient when you're already on a laptop or want a calculator that respects copy-paste. This calculator handles all the standard scientific functions with keyboard input and memory. Working with percentages instead? Use the Percentage Calculator. Need to age-out a date calculation?

How to use this tool
- 1Pick radians or degreesToggle RAD/DEG before doing trig. Most physics and engineering uses radians; geometry classes typically use degrees.
- 2Type the expressionUse the buttons or your keyboard. Parentheses, function names (sin, cos, log, ln), and operators all work. Press Enter to evaluate.
- 3Use memory and historyM+ adds the current result to memory, MR recalls it, MC clears. Past calculations appear in the history panel for reuse.
