Weight Converter

A free online conversion calculator that convert between kilograms, pounds, ounces, and more. Get accurate results instantly without any software installation. Weight measurements vary dramatically across regions and industries: a recipe calls for grams, a gym tracks body weight in pounds, shipping logistics use kilograms, and precious-metal trading references troy ounces. Navigating these systems without a reliable converter risks dosing errors in pharmaceuticals and miscalculated postage in e-commerce. The converter handles kilograms, grams, milligrams, pounds, ounces, stones, metric tons, and carats — covering everything from cooking measurements to precious-metal weighing. Results round to sensible precision per unit. Type a value in any supported unit — kilograms, pounds, ounces, stones, or tons — and every other unit populates immediately. Precision rounds to a sensible number of decimals for everyday use, with an option to extend digits for scientific or metallurgical applications. Weight conversion factors execute as native JavaScript operations within the page, with zero network requests. Whether you are converting medication dosages or confidential shipping manifests, the input values remain on your machine.
