Unit Converter

Unit conversion is translating a measurement from one unit system to another. The world uses two main systems: metric (meters, kilograms, Celsius) used by most countries, and imperial (feet, pounds, Fahrenheit) used primarily in the United States. International work constantly requires converting between them.

Common conversions include length (inches to centimeters), weight (pounds to kilograms), temperature (Fahrenheit to Celsius), volume (gallons to liters), and speed (mph to km/h). Temperature is the trickiest because it uses different formulas rather than simple multiplication — °C = (°F - 32) × 5/9.

This tool covers the most-used categories: length, weight, temperature, area, volume, and speed. Each conversion uses precise conversion factors and handles decimal precision automatically. Useful for cooking, travel, engineering, fitness tracking, and any cross-border collaboration.
