A scientific calculator is an advanced electronic calculator designed to perform complex mathematical operations beyond basic arithmetic. Unlike simple calculators that only handle addition, subtraction, multiplication, and division, scientific calculators include specialized functions for trigonometry, logarithms, exponentials, roots, and statistical calculations.
These calculators are essential tools for students studying mathematics, physics, chemistry, and engineering, as well as professionals in scientific and technical fields. Our online scientific calculator provides all the functionality of a physical scientific calculator with the added convenience of being accessible from any device with a web browser.
This free tool is designed to help students learn mathematical concepts, professionals perform accurate calculations, and anyone who needs advanced mathematical functions. All calculations are performed instantly with high precision, and the calculator works offline once loaded.
Complete set of trigonometric functions including sin, cos, tan, and their inverse functions (arcsin, arccos, arctan). Supports multiple angle modes: degrees, radians, and gradians.
Natural logarithm (ln) and common logarithm (log base 10) functions for exponential calculations, growth models, and scientific computations.
Full memory functionality with MC (clear), MR (recall), M+ (add), M- (subtract), and MS (store) operations for complex multi-step calculations.
Exponentials, powers, roots, factorials, absolute values, and hyperbolic functions for advanced mathematical and scientific calculations.
Click number buttons to enter values, use operator buttons (+, -, ร, รท) for arithmetic operations, and press = to calculate results. Use the C button to clear and the delete button to remove the last digit.
First, select your angle mode (DEG, RAD, or GRAD). Enter your angle value, then click the desired function (sin, cos, tan). For inverse functions, press SHIFT first, then the function button.
Use your keyboard for faster input: numbers 0-9, operators (+, -, *, /), Enter or = for calculation, Escape to clear, Backspace to delete, and parentheses for grouping expressions.
Store intermediate results using memory functions: MS to store, MR to recall, M+ to add, M- to subtract, and MC to clear memory. This is helpful for multi-step calculations.
