How many pounds are there in a kilogram?
There are 2.2 pounds in a kilogram (2.2 lbs in 1 kg) because 1 kilogram is defined as the mass of one liter of water and the same amount of water equals to 2.2 pounds.
How to convert from kilograms to pounds?
To convert kilograms to pounds, multiply the number of kilograms "x" by 2.2.
For example, to find out how many pounds (lbs) there are in a kilogram and a half, multiply 1.5 by 2.2, that makes 3.3 lbs in 1.5 kilograms.

What is a kilogram (kg)?
Kilogram (kg) is a metric system mass unit. 1 kilogram equals to 2.20462 pounds, 35.274 pounds or 1000 grams. The abbreviation is "kg".
Kilogram Definition (Before May 2019):
Kilogram is equal to the mass of the international prototype (platinum-iridium cylinder kept in France) of the kilogram. The kilogram prototype is also known as "Le Grand K".
Kilogram Redefinition (After May 2019):
On 16 November 2018, for the most accurate measurement, the scientists agreed that the SI base unit definitions should not be based on the physical objects but instead based on fundamental constants of nature that does not change over time, such as Planck constant etc.
With the new definition, the Kibble balance will be used to measure the mass of the kilogram. When you place a weight on the Kibble balance, the machine produces an electric current proportional to Planck’s constant. With Planck’s constant set, the kilogram will correspond to a specific amount of current in the Kibble balance.
Based on this, the redefinition of kilogram is:
"Kilogram is defined by taking the fixed numerical value of the Planck constant h to be 6.62607015×10−34 when expressed in the unit J⋅s, which is equal to kg⋅m2⋅s−1, where the metre and the second are defined in terms of c and ΔνCs."
With the new definition, the kilogram also depends on the definitions of the second and the metre.
What is a pound (lb)?
Pound (lb) is an imperial system mass unit. After US Customary system is adopted, it remained the same. The pound dates back to the Roman empire and at that time it was called "libra" (that's where the "lb" abbreviation comes from). After the metric system, 1 pound is defined as exactly 0.45359237 kilogram. The abbreviation is "lb".
The list for your reference:
1 Kilogram = 2.20462 Pounds
1/8 kg = 0.275 lb
1/4 kg = 0.55 lb
1/2 kg = 1.1 lb
1 kg = 2.2 lbs
3/2 kg = 3.3 lbs
2 kg = 4.4 lbs
5/2 kg = 5.5 lbs
