How to use the weight converter
This weight converter lets you switch between the most common metric and imperial units of mass. Choose the unit you are converting from on the left and the unit you are converting to on the right, enter a numeric value, and click "Convert" to see the result instantly. A "Swap" button reverses the direction so you can verify the conversion both ways. The converter supports kilograms, grams, milligrams, pounds, ounces, stones, metric tons, and US short tons.
Weight conversion comes up constantly in cooking, fitness, shipping, and international trade. A kilogram equals roughly 2.205 pounds, an ounce is about 28.35 grams, and a stone (commonly used in the UK for body weight) is 14 pounds or about 6.35 kilograms. If you are comparing product labels, tracking your body weight across different scales, or calculating shipping costs, this tool applies the exact conversion factors so every result is precise to eight decimal places.
The tool runs entirely in your browser with no sign-up, no download, and no ads blocking the view. It is designed to be mobile-friendly: the two-column layout stacks on small screens, inputs are touch-friendly, and the result is shown clearly alongside the input so you can compare both values at a glance. Whether you are a home cook, a gym-goer, a student, or a logistics professional, this weight converter gives you fast, accurate results wherever you are.
For each conversion the tool also displays the unit ratio (for example, "1 Kilogram = 2.20462 Pound"), which is handy when you need to memorize or quote the factor in a report, recipe, or classroom.
