Convert between kilograms, pounds, ounces, and more
The weight or mass converter is a versatile tool that allows conversions between the main weight measurement units used globally, including the metric system (kilograms, grams, milligrams, metric tons) and the imperial system (pounds, ounces, tons). Essential for cooks, athletes, scientists, merchants, healthcare professionals, and anyone who needs precise weight conversions for recipes, exercise, international trade, scientific analyses, or personal health tracking.
Our tool uses standard conversion relationships between mass units to provide instant precise results:
Enter the weight or mass value you want to convert in the numeric input field.
Select the source weight unit (kilogram, pound, ounce, etc.) from the 'From' selector.
Choose the desired target unit in the 'To' selector and get the automatically converted result.
Copy the result to use in your recipes, workouts, reports, or any other application you need.
This tool is indispensable in multiple professional and personal situations:
Cooks and chefs following international recipes who must convert ingredients between grams, ounces, pounds, and kilograms.
Athletes and nutritionists monitoring body weight, nutritional intake, and training loads in different units.
Merchants and importers handling products with specifications in different weight systems to comply with local regulations.
Scientists and laboratory technicians performing precise measurements who need to convert between milligrams, grams, and other metric units.
For cooking: 1 pound equals approximately 454 grams, and 1 ounce about 28 grams, useful for American recipes.
For body weight tracking: 1 kilogram equals approximately 2.2 pounds, a common factor in gyms and weight loss programs.
A metric ton (1000 kg) is different from an imperial ton (approximately 907 kg), important in logistics and transportation.
Mass is the amount of matter in an object (measured in kg or lb), while weight is the gravitational force on that mass. In everyday use, the terms are used interchangeably, although technically they are different.
One kilogram equals approximately 2.20462 pounds. For quick mental conversion, you can multiply kilograms by 2.2 to get pounds.
Multiply the ounces by 28.35 to get grams. For example, 8 ounces × 28.35 = 226.8 grams. Many recipes use 1 oz ≈ 30g as a practical approximation.
