About Unit Converter
Convert between common units across eight measurement categories: length (meters, feet, miles, inches), mass and weight (kilograms, pounds, ounces, stone), temperature (Celsius, Fahrenheit, Kelvin — with absolute-zero validation), area (square meters, acres, hectares), volume (liters, US gallons, cups, fluid ounces), speed (km/h, mph, knots), time durations (seconds, minutes, hours, days, weeks), and digital storage. Storage correctly distinguishes SI decimal units (kB, MB, GB — powers of 10) from IEC binary units (KiB, MiB, GiB — powers of 2). Results update instantly as you type. Everything runs locally in your browser — no values are ever sent to a server.
