Mastering of kilogram to pound conversion: Definition, formula, and calculations

Kilogram to pound conversion is the conversion of one measurement unit system into another measurement unit system without the difference in its appearance whether liquid, solid, or gas. Both represent the mass of solid quantity but in different measurement systems.

A kilogram is the base unit of mass in the SI (international system) unit system while a pound is the imperial or US-customary system unit of mass. Many people worry about the conversion from kg to pound but don’t worry about that you are at the right place.

In this article, you will explore the basic definition of the kilogram & pound and the formula for conversion from kg to pound. Moreover, we will provide different examples.

What is a kilogram?

A kilogram is the unit of mass of solid objects in the international number system or metric system. Kilograms have a fixed numerical value in the form of Planck’s constant such as 6.62 × 10^-34. It is also determined as the mass of one liter of water at its freezing point but it also involves the fundamental physical constant. It is represented by the symbol “kg”.

In the 18^th century kilogram was represented by a solid platinum cylinder for the measurement of the mass of the volume of the water. After the 18^th century, the standard kilogram was introduced also a solid cylinder which is made of platinum-iridium alloy.  

But it's difficult to measure the exact kilogram amount of any physical thing by comparing it with the platinum-iridium artifact. Also noted the standard copies of the artifact are slightly lighter than the standard kilogram artifact; this addresses the issue in measurement of the weight.

To remove this difficulty in 2018 kilograms were equal to the value of the plank constant rather than the physical artifact. This removes the error of artifacts and generates a standard in the whole world for the measurement of the weight in kilograms and facilitates conversions such as grams to moles.

What is a pound?

A pound is the unit of mass or weight measurement in the British imperial and United States customary weight systems. One pound is equal to the 16 ounces, 7,000 grains, and 0.4535 kg in the customary system.

It is represented by the symbol “lbs” which is taken from the Roman word “libra”. In medieval England, many calculations or derivation values were proposed for libra. One of the latest values was the Tower pound which is equal to the 5400 grains or 0.350 kg that was used to measure the weight of the precious metal or drugs.

Moreover, the mercantile pound and troy pound were also proposed for the weight of precious metals like silver and gold. The 16-ounce was adopted for the weight of precious metals like gold and silver due to increased trade in France in the 16^th century.

Overall the metric system uses the kilogram as the unit of mass but there are other units also exist that are used by different countries in various contexts such as gram, carat (for gemstones), and atomic mass unit (for chemical products).

Formula of Kilograms to Pounds Conversion

The mathematical formula of the “kg to lbs conversion” can be stated as,

1 Pound (1 lbs) = 1 kilogram (kg) × 2.2046

In general, the formula can be stated as,

Pound (lbs) = “n” kilogram (kg) × 2.2046

This formula is based on the conversion factor of “2.2046” which is the weight of one pound in kilograms. If you want to convert the kg to pounds then simply multiply the “kg” with factor “2.2046” and if you want to convert the pound to kg then simply divide the pound value with factor “2.2046”.

How to convert kg to Pounds?

If you want to convert the mass from kg to pound then simply follow the below simple steps.

• First, note the kilogram value from the given data.
• Secondly, to convert from “kg to lbs” multiply the kilogram value with the “2.2046” factor by using its formula and get your final result.

Note: it is important to note that the factor “2.2046” is kept in mind for the conversion of kilogram into pounds. Also, remember to use the correct symbol of kilogram and pounds.

Example: Determine the value of “70 kg” in pounds by using its formula.

Solution:

Step 1: Note the value of the kilogram.

Given data = 50 kg

Step 2: Put the values in the pound conversion formula.

Pound (lbs) = “n” kilogram (kg) × 2.2046

        = 50 × 2.2046

Pound (lbs) = 110.23 lbs.

Examples

Here we provide examples of the complete conversion process of kg into lbs with complete steps.

Example 1: Convert the 30 kg into lbs value.

Solution:

Step 1: Note the value of the kilogram from the given data.

Kilogram = 30 kg

Step 2: Put the value of “kg” in the pound conversion formula.

Pound (lbs) = “n” kilogram (kg) × 2.2046

        = 30 × 2.2046

Pound (lbs) = 66.138 lbs.

Alternatively, you can use a Kg to Pounds Converter to make calculations faster than manual calculations.

 

Example 2: Convert the 45.7 kg into pounds value.

Solution:

Step 1: Note the value of the kilogram from the above data.

Kilogram = 45.7 kg

Step 2: Put the value of “kg” in the kg to pounds conversion formula.

Pound (lbs) = “n” kilogram (kg) × 2.2046

        = 45.7 × 2.2046

Pound (lbs) = 100.75 lbs.
