Math Calculators
Scientific Calculator
Advanced scientific calculator with trigonometric, logarithmic, and statistical functions. Features include sin, cos, tan, logarithms (log, ln), exponential functions, square roots, powers, nested parentheses, and proper order of operations (PEMDAS). Perfect for engineering, physics, and advanced mathematics calculations with support for degrees and radians.
Fraction Calculator
Perform calculations with fractions, mixed numbers, and improper fractions. Add, subtract, multiply, and divide fractions with automatic common denominator finding and result simplification. Convert between mixed numbers and improper fractions, transform fractions to decimals, and get step-by-step solutions perfect for students learning fraction operations.
Percentage Calculator
Calculate percentages, discounts, markups, and percentage changes with precision. Find percentage of numbers, calculate percentage increase or decrease, determine sale prices and discount amounts, reverse calculate original values, and compute profit margins. Essential for business, finance, shopping, and academic percentage calculations.
Conversion Calculator
Convert between units of length, weight, volume, temperature, and more with precise conversion factors. Transform metric to imperial units (meters to feet, kilograms to pounds, liters to gallons), convert temperatures (Celsius, Fahrenheit, Kelvin), and handle cooking measurements. Perfect for international travel, cooking recipes, and scientific calculations.
Triangle Calculator
Calculate triangle area, perimeter, angles, and sides using various methods including Heron's formula, Law of Sines, and Law of Cosines. Works with all triangle types (right, equilateral, isosceles, scalene), finds missing angles and sides, and provides comprehensive geometric solutions perfect for geometry homework and construction projects.
Standard Deviation Calculator
Calculate standard deviation, variance, mean, and identify outliers in datasets with comprehensive statistical analysis. Supports both population and sample standard deviation (with Bessel's correction), computes quartiles, median, mode, range, and uses IQR or z-score methods for outlier detection. Essential for research, quality control, and data analysis.
Random Number Generator V3
Generate verifiable random numbers with customizable ranges and scientific precision using cryptographically secure algorithms. Create single or bulk random numbers within specified min/max ranges, ensure uniqueness or allow duplicates, and produce truly unpredictable results perfect for statistical sampling, simulations, lottery systems, and scientific research applications.
