Use this weight converter to switch instantly between the main metric and imperial mass units. Enter a value in tonnes, kilograms, grams, milligrams, pounds or ounces and see the equivalent in all other units at once. It is useful for recipes, parcel shipping, gym tracking, laboratory work and any situation where measurements move between different unit systems.
1 kilogram = 2.20462 pounds. So 70 kg ≈ 154.3 lbs.
Mass is the amount of matter in an object (measured in kg, g). Weight is the gravitational force on that mass (measured in Newtons). In everyday language they are used interchangeably.
Pounds and ounces are still common in some countries for body weight, food packaging and recipes. Kilograms and grams are the standard metric units used in most of the world.
Method: Convert input to grams (base unit), then to each target. Key ratios: 1 kg = 1,000 g | 1 lb = 453.592 g | 1 oz = 28.35 g | 1 tonne = 1,000,000 g.
Example: 5 kg = 5,000 g = 5,000,000 mg = 11.023 lb = 176.37 oz = 0.005 tonnes.
