We have mentioned a little about kilograms and pounds yet but this topic is not exhausted. This will be very practical article dedicated to calculations **how much kg is lbs**, for instance, **how many kg is 130 pounds** and many more. Do you want to know how to calculate any amount of pounds to kilograms? Keep reading.

Before we move on to the main topic of our article, it means **how many kg per pound** and calculations lbs to kg step by step, we want to give you some basic information about these two units.

**The pound** is a unit of mass. The most common kind of pound is avoirdupois pound. The avoirdupois ounce can be divided into 16 ounces. In abbreviated form it is written as lb or “.

This unit is used mostly in the United States and British (also known as Imperial) customary systems of measurement. That’s why you can see the pound in usage mostly in the United States and the United Kingdom.

The pound is used in different areas. Firstly, in the United States and the United Kingdom in pounds is measure body weight. Pounds are also used to measure food products, such as flour or sugar.

**The kilogram** is also a unit of mass. The symbol of a kilogram is kg.

It is a basic unit in the International System of Units (in abbreviated form SI). This unit is used mostly in continental Europe.

The kilogram is used, as a pound, to measure body weight. This unit is also used in engineering and science. Of course, the kilogram is used in everyday life too, for instance, to give product weight.

You know a little about these two units so we can move on to the more practical part – **how much kg to lbs**.

Before we give you a formula to calculate lbs to kg, you have to know **how many kg is one lbs** and how many lbs is one kg. Have a look:

- 1 lb = 0.45359237 kilograms,
- 1 kg = 2.20462262 pounds.

You can also see these results in a table down below:

Pounds (lbs) | Kilograms (kg) |

1 | 0.45359237 |

2.20462262 | 1 |

Now you know **how many kg is equal to one pound** so this is the time to show you the **formula** which you will need to your calculations.

So what is a **formula** to calculate **how many kg per lbs**? We gave it down below:

**Amount of pounds * 0.45359237 = the result in kilograms**

This is a first, full version of a formula. If you want to make your calculations easier, you can use shorter form of a formula. You can find it down below:

**Amount of pounds * 0.45 = the result in kilograms**

We will show you calculations step by step using both of them. We will also make a comparison of obtained results. Keep reading!

So try these formulas. First example we will explain you step by step. Then we will show you other examples in shorter form.

Let’s start with a full formula. **How many kg is one lbs**? You have to multiply number of pounds by 0.45359237. So multiply 1 by 0.45359237. It gives 0.45359237. So 1 lb is equal 0.45359237 kg. If you round it off to two decimal places, the final result is equal 0.45 kg.

Now try shorter form of a formula. **How many kg in one lbs**? Multiply 1 by 0.45. It gives 0.45. So 1 lb is equal 0.45 kg.

As you can see, the difference in this case is not significant but if you calculate bigger numbers, the difference will be more significant.

You can compare these two results using a charts given down below. Have a look.

In the first chart is the result calculated using a full formula.

Pounds (lbs) | Kilograms (kg) |

1 | 0.45359237 |

In the second chart is the result calculated using a short formula.

Pounds (lbs) | Kilograms (kg) |

1 | 0.45 |

Now you know **how much is kg to lbs** and how to use these two formulas so we can move on to the next examples.

In this part of the article we want to show you a few more examples in a short form. Firstly, we will show you calculations for bigger numbers of pounds, it means numbers equal 100 lbs and over.

Have a look on examples calculated using a full formula.
