How to Use the Weight Converter
Enter a value like 70, select "Kilograms" from the From dropdown and "Pounds" from the To dropdown, then click "Convert." You'll see 154.324 pounds — the approximate weight of an average adult male. The default setting converts 1 kilogram to 2.20462 pounds. You can convert between kilograms, grams, pounds, ounces, tons, and stones. Fitness tracking, cooking, shipping, and medical applications all rely on accurate weight conversions. If you're following a US recipe that calls for 8 oz of flour but your scale only shows grams, enter 8 ounces to get 226.796 grams.

How to Interpret Your Results
Body weight across countries: If you weigh 154 lbs and visit a doctor in Europe, you'll need it in kilograms: 154 / 2.205 = 69.85 kg. A healthy BMI range of 18.5-24.9 for a 1.75m person corresponds to 56.7-76.3 kg or 125-168 lbs. Fitness apps often default to kilograms or pounds depending on your region, so knowing your weight in both systems is useful.
Shipping and postage: International shipping labels require weight in kilograms even if you're in the US. A 5 lb package equals 2.27 kg. Conversely, European online shoppers ordering from US stores need to convert product weights from pounds to kilograms to estimate shipping costs. A typical suitcase weight limit of 50 lbs equals 22.68 kg, and 23 kg is the standard checked bag limit for most airlines.
Kitchen and baking: Professional bakers weigh ingredients for consistency. A cup of all-purpose flour weighs 125 grams or 4.4 ounces. European recipes list flour in grams while American ones use cups, so a recipe calling for 500 g flour equals about 4 cups. Butter is sold in 1 lb blocks in the US (454 g) or 250 g blocks in Europe. Converting between them helps avoid baking disasters.
