Kilograms and pounds are the two most widely used units of weight worldwide, and converting between them is one of the most common unit conversions people need. The kilogram is the standard unit of mass in the metric system, used by virtually every country on earth for trade, science, and everyday measurement. The pound remains the primary weight unit in the United States and is still commonly understood in the UK, particularly for food, babies, and parcels. One kilogram equals approximately 2.2046 pounds. This relationship is defined precisely: the international pound is defined as exactly 0.45359237 kilograms. While the UK officially uses kilograms for commercial purposes, pounds persist in informal usage and in certain regulated contexts such as precious metals. Whether you are following an American recipe that lists ingredients in pounds, checking the weight of a parcel against Royal Mail limits shown in kilograms, or comparing produce prices at a market, this converter gives you an instant answer in both directions, along with ounces and grams for finer detail.

How It Works

The conversion uses the internationally defined factor: 1 kg = 2.20462 lbs (or equivalently, 1 lb = 0.453592 kg). Kilograms to Pounds: Pounds = kg x 2.20462 Ounces = pounds x 16 Example: 3 kg = 3 x 2.20462 = 6.614 lbs = 105.82 oz Pounds to Kilograms: kg = lbs / 2.20462 (or lbs x 0.453592) Grams = kg x 1,000 Example: 10 lbs = 10 / 2.20462 = 4.536 kg = 4,536 g A quick mental shortcut: double the kg and add 10% to estimate pounds. For example, 7 kg: 7 x 2 = 14, plus 10% (1.4) = 15.4 lbs (actual: 15.43 lbs).

Worked Examples

Example 1: Checking Royal Mail parcel weight

Inputs: Kilograms: 2. Direction: kg to lbs.

Pounds = 2 x 2.20462 = 4.409 lbs.
Ounces = 4.409 x 16 = 70.55 oz.
Grams = 2 x 1,000 = 2,000 g.

Result: 2 kg equals 4.41 pounds or about 70.5 ounces. Royal Mail small parcel limit is 2 kg.

Example 2: Converting an American recipe ingredient

Inputs: Pounds: 1.5. Direction: lbs to kg.

Kilograms = 1.5 / 2.20462 = 0.6804 kg.
Grams = 0.6804 x 1,000 = 680 g.
Ounces = 1.5 x 16 = 24 oz.

Result: 1.5 pounds of flour equals 680 grams or 0.68 kg.

Example 3: Converting baby birth weight

Inputs: Kilograms: 3.4. Direction: kg to lbs.

Pounds = 3.4 x 2.20462 = 7.496 lbs.
Whole pounds: 7. Remaining ounces: 0.496 x 16 = 7.9 oz.

Result: 3.4 kg equals 7 lbs 8 oz, a typical birth weight in the UK.
