Have you ever wondered how to convert kilograms to pounds? You might find yourself pondering this question over a kitchen counter while in the middle of making a recipe.

You might have come across recipes that use kilograms and pounds as measuring units alternatively. Although both of these units measure weight, they are not the same.

And contrary to what some believe, kilograms and pounds cannot be used interchangeably as they weigh differently. These units not only differ in their name, but they also differ in terms of the weight they represent as well.

Before we move forward to the question at hand, “How to convert Kilograms to pounds?” let’s have a brief introduction of both of these units and understand how they are different from each other.

What is a Kilogram?

The kilogram is a base unit of mass or weight used in the International System of Units (SI Units) and is abbreviated as “kg.”

The current unit of kg is based on a fixed numeric value of the Planck Constant. The specified value for the Planck Constant roughly equals 6.62607015 × 10-34.

The word kilogram was derived from the French word “kilogramme,” which means thousand in English. One interesting fact about kilogram is that it is the only SI unit that uses its own SI prefix. The definition of the kilogram was revised in 2019, but no changes were made to the weight it measured.

A Brief History of the Kilogram

In the late 18th century, 1 kg equaled the weight of one solid platinum cylinder. Measuring one kg by the mass of the volume of water showed inconsistent and imprecise results, so this measurement method was discarded.

The standard measurement of the kg was revised in 1889 from a solid platinum cylinder to another cylinder made up of platinum-iridium alloy.

In 2011, the standard definition of kg was revised once again. This time, instead of associating its value to an object, the kilogram was declared a fundamental physical constant instead of a physical artifact.

What are the Current Uses of the Kilogram?

The kilogram is used worldwide in most countries, including the UK, with a few exceptions like the United States.

It is used in almost every field, including military, government, science, and industries. In the United States, the kilogram is used in these fields, but the pound is preferred in everyday usage.

What is a Pound?

The pound is another unit to measure mass and weight. It is denoted by “lb” and is used in Imperial and US Customary unit systems. The pound is precisely equal to 0.45359237 kilograms. Today the avoirdupois pound is commonly used.

A Brief History of the Pound

Just like the kilogram, the definition of the pound also changed many times during history. It was finally revised to the avoirdupois pound that is currently in use.

This system was first used during the 13th century and was updated to its current form in 1959. This unit was based on a system that used a standardized physical pound weighing equal to a prototype weight.

One reason for the popularity of this system over other systems is thought to be the fact that the prototype used for the pound could be divided into three even divisions, including 8, 4, and 2. In contrast, the other system is divided into 10, 12, or 15 subdivisions, which is a bit inconvenient.

The original pound was approximately equal to 453 grams and was used in English-speaking countries before the 20th century.

The different values of the pound used during different periods of history were unified in the UK by the Weights and Measurements Act of 1976.

According to this act, the kilogram equals 1045.6223704 avoirdupois pounds. This was declared to be used as the international pound all over the globe, except for the United States and Liberia.

What are the Current Uses of the Pound?

The pound is a popularly used unit in the United States. It is mainly used to measure body weight. As mentioned above, the kilogram is widely used in the UK, but a few variants of the pounds also have applications in different regions of this country.

One of these applications is the labeling of food packaging. However, it is mandatory to display the metric values as well.

Therefore, apart from using pounds to measure body weight, another unit is also used in the UK for this purpose. This unit is called the stone and is made up of 14 pounds.
