Rounded to six significant digits.
Multiply the kilogram value by the number of pounds in one kilogram; the result is the weight in pounds. Going the other way, you divide pounds by that same factor to get kilograms.
Convert the kilograms to pounds first, then split that pound figure into whole stones plus the leftover pounds, since a stone is a fixed number of pounds. The stone value is the whole-number part of the division and the remainder is the extra pounds.
Take the weight in its original unit and multiply by the conversion factor to pounds — kilograms and grams each have their own factor to pounds. For ounces you divide instead, because ounces are smaller than a pound.
Multiply the value by the ratio between the two units, making sure the old unit cancels out and the new one remains. If you convert to a smaller unit the number gets bigger, to a larger unit it gets smaller.
Most digital scales have a unit button or a setting menu where you switch between kg, lb and st; hold or press it until the display shows lb. If the scale has no switch, weigh yourself in kilograms and multiply by the kilogram-to-pound factor.
Multiply the pounds by the number of grams in one pound. To go back, divide the grams by that same factor.
Multiply by the factor that links your unit to grams — kilograms, pounds and ounces each have their own. Since grams are a small unit, the resulting number will be larger than what you started with.
Divide the pounds by the pound-per-kilogram factor, or for a rough mental estimate halve the pounds and take a bit off the result. The quick estimate is close enough for everyday use, but use the exact factor for recipes or medication.
One pound equals a fixed number of grams defined by the international avoirdupois pound, so you multiply any pound value by that constant to get grams. The same constant works in reverse when you divide grams by it.

One of the most common reasons people use a weight converter is for body weight. If you are using a fitness app based in the United States, it may ask for your weight in pounds. Someone weighing 70 kilograms, for example, weighs approximately 154.3 pounds. Our converter handles this instantly, making it easy to switch between measurement systems without confusion.
When ordering products online from international retailers, weight is often listed in different units depending on the country of origin. A product described as weighing 5 pounds in an American store weighs approximately 2.27 kilograms. Understanding this helps you estimate shipping costs and avoid surprises at customs.
American and British recipes frequently use ounces and pounds instead of grams. If a recipe calls for 12 ounces of flour, that equates to roughly 340 grams. Our weight converter helps home cooks and professional chefs alike adapt recipes from any country without guesswork.
In strength training and powerlifting, weights are often described in pounds – especially in American content. A classic 135-pound barbell weighs approximately 61.2 kilograms. Athletes who consume content from multiple countries benefit from instant conversions to keep their training on track.
Engineers, researchers, and logistics professionals frequently need to convert between metric tons, short tons, and kilograms. Our tool handles these large-scale conversions with the same precision as everyday measurements, making it suitable for professional use as well.
