Mathematics Calculators
Advanced mathematical calculators for percentages, scientific functions, fractions, GCD/LCM, and unit conversions. Solve complex problems with ease.
Percentage Calculator
A comprehensive percentage calculator with three calculation modes: find X% of a number, determine what percentage one number is of another, and calculate percentage change or difference. Features step-by-step explanations to help you understand percentage calculations, supports both increase and decrease calculations, and provides clear examples for educational purposes.
Scientific Calculator
A full-featured scientific calculator supporting standard arithmetic operations, trigonometric functions (sin, cos, tan), logarithms (log, ln), exponentials, square roots, power functions, and scientific notation. Includes memory functions, angle mode switching (degrees/radians), and advanced mathematical constants like π and e. Perfect for students, engineers, and scientists.
Fraction Calculator
Perform all basic arithmetic operations with fractions including addition, subtraction, multiplication, and division. Supports mixed numbers, improper fractions, and automatically simplifies results to lowest terms. Shows step-by-step solutions to help understand fraction arithmetic, handles complex fraction problems, and includes conversion between mixed numbers and improper fractions.
GCD/LCM Calculator
Calculate the Greatest Common Divisor (GCD) and Least Common Multiple (LCM) for two or more numbers using the Euclidean algorithm. Supports multiple numbers input (comma-separated), shows the calculation process step-by-step, and explains the relationship between GCD and LCM. Essential for fraction operations, solving ratio problems, and number theory applications.
Unit Converter
Convert between hundreds of units across multiple measurement categories with our comprehensive unit converter. Supports length, weight, volume, temperature, area, speed, pressure, energy, and more. Features common unit shortcuts, precise conversion factors, and bidirectional conversion. Includes both metric and imperial systems with scientific and engineering units. Essential for cooking, construction, science, and international commerce.
