Converting Pounds to Kg

Pound (lb) and Kilogram (Kg) are units of measurement of mass in different measuring systems. Pound is used in the imperial system, while kg is used in the International System of Units (SI). 1 pound is equal to 0.453 kg. To convert Pounds to Kg, multiply the value of pounds by 0.453kg. 

In this blog, you will learn about pounds and kilograms and how to convert pounds to kilograms in easy steps. Let’s first learn about lb and kg.

Pound  

The pound is a unit of mass or weight used primarily in the imperial and U.S. customary systems. It is one of the most commonly used non-metric weight units in the world, especially in the United States. 

The pound is abbreviated as lb or lbs. The abbreviation ‘lbs’ comes from the Latin word libra, which means balance or scale. The original term is ‘libra pondo’, meaning ‘a pound by weight.’ Over time, the word ‘pound’ evolved from ‘pondo’, while ‘lb’ was retained as the standard abbreviation.

Kilogram 

The kilogram is the standard unit of mass in the International System of Units (SI). It is abbreviated as ‘kg’. The word ‘kilogram’ is derived from the French word ‘kilogramme’, which stems from the Greek word ‘khilioi’, meaning "a thousand", and the Latin term ‘gramma’ means ‘a small weight’. 

Relation Between Pound and Kg

A pound (lb) is an imperial unit of mass, while a kilogram (kg) is a metric unit of mass or weight. We can easily convert pound to kg. 1lb is equal to 0.453592 kg, and 1 kg is equal to 2.20462lbs. 

How to Convert Pounds to Kilograms

Pounds and kilograms are interconvertible. We can easily convert pounds to Kilograms using different methods. There are two methods to convert pounds (lb) to kilograms (Kg). 

• Multiplying the number of pounds by 0.454
• Dividing the number of pounds by 2.2046

You will learn both methods of conversion in detail. 

Multiplying the Number of Pounds

We know that 1 pound (lb) is equivalent to 0.45359 kilograms (kg). So, it can be converted into kg by multiplying the number of pounds by 0.45359. 

The formula to convert lb into kg by multiplying is given as; 

mass(kg) = mass(lb) × 0.45359237

Let’s understand it with the help of an example. 

Convert 5 pounds to kg.

We will use the formula to convert lb to kg.

mass(kg) = mass(lb) × 0.45359237

We will substitute the values in the formula.

mass(kg) = 5 × 0.45359237

mass =2.26796185 kgs

So, 5 pounds is equal to 2.267 kgs. 

Hence, we easily converted pounds into kilograms. 

Let’s look at some of the Pound to Kilogram conversion. 

Example 1

Convert 20 lbs to kilograms.

mass(kg) = mass(lb) × 0.45359237

mass(kg) =20 × 0.45359237

20 lbs =9.07184 kgs

Example 2

Turn 15 lbs into kgs.

We can turn lbs into kg by using the given formula. 

mass(kg) = mass(lb) × 0.45359237

Substitute the values in the formula. 

mass(kg) =15 × 0.45359237

15lbs =6.80388555 kgs

Example 3

Show 30 Pound in Kg. 

The same formula will be used to change pounds in kilograms. 

mass(kg) = mass(lb) × 0.45359237

mass(kg) = 30 × 0.45359237

30lbs =13.6077711kgs

Dividing the Number of Pounds

1 kilogram is equal to 2.2046 pounds. So, we can turn pounds into kilograms by dividing the value of pounds by 2.2046. The formula for conversion by division is given as;

Pounds 2.2046=kg

Let’s understand it through examples.

Example 1

Convert 12 lb to kg. 

We will use the formula of conversion.

Pounds 2.2046=kg

Substitute the values in the formula. 

12 2.2046=kg

5.4431=kg

12lbs=5.4431kgs

Example 2

Change 60 pounds into kilograms

Pounds 2.2046=kg

60 2.2046=kg

27.2155=kg

60Pounds=27.2155kgs

Example 3 

Turn 100 lb to kilograms.

Pounds 2.2046=kg

100 2.2046=kg

45.3592=kg

100Pounds=45.3592kgs

So, we learned converting pounds to kilos in weight. Now you can convert any value from lb to kg. 

Conclusion 

Pounds and kilograms are interchangeable units of measurement of mass or weight in different systems of units. One pound is equivalent to less than half of one kg. Dividing and multiplying the value of pounds by the value of kg are two methods of converting lb to kg.
