About the KG to LBS Converter
Kilograms are used for body weight, luggage and groceries almost everywhere, while pounds are the everyday unit in the United States and are still common in the UK and elsewhere. This converter changes kilograms into pounds, or pounds into kilograms, in one step. For every result it also shows the weight as pounds and ounces and as stone and pounds, so you can read it in whichever way suits you. A short table lists common weights from 1 to 100 kg for quick reference. The conversion uses the exact definition of the pound, 0.45359237 kilograms, so the answers are precise.

Where this conversion helps
Travellers check luggage limits, which airlines quote in kilograms or pounds. Gym-goers convert weights between plates marked in kilograms and ones marked in pounds: a 20 kg bar is 44.1 lb, and a 45 lb plate is 20.4 kg. Parents track baby weights quoted in pounds and ounces on one side of the Atlantic and kilograms on the other. Cooks convert bags of flour and sugar.
Many people do this conversion for health reasons, so a few cautions help. Scales differ by a few hundred grams, clothes and time of day change your weight by a kilogram or more, and weight on its own says little about health. If you track your weight, use one scale, weigh yourself at the same time each day, and compare weekly averages. Convert only the final figure, rather than converting each reading, so rounding errors stay small and the trend remains clear.
The same conversion applies to products: a 2.5 kg bag of rice is 5.51 lb, a 20 kg suitcase is 44.1 lb and a 23 kg airline limit is 50.7 lb. Shops in the US may label the same bag 5 lb and a European one 2.5 kg, which are close but not equal. When you compare prices per pound with prices per kilogram, convert one of them first. A price of 3 per pound is 6.61 per kilogram, so a bag marked 6 per kilogram is the cheaper one.
Rounding tips
For body weight, one decimal place is enough. For shipping, round up to the next unit the carrier uses. For scientific work, keep more digits and round at the end. If you need to show both units in a document, write the main one first and the conversion in brackets, for example 70 kg (154 lb).
