Pounds (lbs) and kilograms (kg) are two commonly used units of measurement in our daily lives. Whether we’re shopping for groceries or discussing a person’s weight, these units are often used interchangeably. However, converting pounds to kg or vice versa can sometimes be a bit challenging.
The good news is that you don’t need to be a maths wizard to do these conversions. In fact, you don’t even need to do the calculations yourself. Square Yards has developed a straightforward lbs to kg calculator. Just input the values, and it will handle the conversion for you, making things much easier.
But in case you want to learn how to convert the digits, then we have listed all the information that is there about pounds (lbs) and kilograms (kg). So, go ahead and soak in the knowledge.
What is a Pound (lbs)?
In the British Imperial and United States Customary Systems of Measurement, the pound serves as the unit of mass. Among various definitions of the pound, the international avoirdupois pound is the most prevalent today. Legally, 1 pound in kg is 0.45359237, divided into 16 avoirdupois ounces. If you want to take a test, then try to calculate 2 pounds in kg in your head, you will get to know where you are in the process of learning. Anyways, the pound is often represented by the symbols “LB” or “LBS,” with “LBM” being an alternative symbol. Also, “℔” or “″̶” is used, particularly for the apothecaries’ pound.
Current Use of Pound
A pound is a unit used to measure the weight of the objects and human body. Specifically, the unit is used throughout the U.S and is preferred over kilograms (the basic unit of mass). In the past, multiple versions of the pound were available throughout the UK and it majorly stays within the International System of Units or SI units.
The pound is still used to label packaged items or food products. Just like in the U.S, the pound is preferred over Kilograms for measuring body weight in the UK.
Origin of Pound
The term ‘Pound’ comes from the Roman libra, symbolised as lb, and was equivalent to about 328.9 grams. It derives from the latin word for “balance or scales”. In mediaeval England, various versions of libra competed for acceptance, but the globally recognised Pound is based on the metric system. This Pound has linguistic ties to Dutch Pond, German Pfund, and Swedish Pound, although these historic units have been replaced by the metric system. The use of the unit “Pound” reflects the historical blending of weight and mass concepts, leading to distinctions like “Pound-Force” and “Pound-Mass” in modern terminology.
What is Kilogram (kg)?
The Kilogram (KG), often called “kilo,” is a crucial unit of mass in the metric system (International System of Units or SI). It’s used in various fields like science, engineering, and commerce. In simple terms, it’s what we use to measure how heavy things are, from common objects to food like flour and veggies. Even when we talk about a person’s weight, we’re using kilograms. The kilogram’s definition in science involves some complex stuff with atomic frequencies and constants, but in everyday life, it’s a way to quantify how heavy things are.
Current Use of Kilogram
Since, a kilogram is an SI unit for the measurement of mass, it finds several applications in engineering, scientific, and commercial fields. India, among the other few countries, uses Kilograms as the standard unit to measure the weight of a person. Although the unit is used by almost every country across the world, there are a few like the U.S and the UK, that prefer the Pound over Kilograms.
Origin of Kilogram
A kilogram was supposed to be the exact mass of 1,000 cubic centimetres of water, but it’s not exactly that, although it’s pretty close. On the other hand, 1 lb to kg is 0.45359237 so you can calculate how much 10 pounds in kg are in real time.
Back in the late 1700s, scientists defined the kilogram using a solid platinum cylinder. In 1795, they said it should be the same as the mass of one litre of water. The modern definition is still super close to that original idea, accurate within 30 parts per million. So, a kilogram helps us measure how heavy things are, like water, and it’s really close to what they first thought it should be.
The Relationship between lbs and Kilogram
The relationship between the pound and kilogram can be understood easily in terms of the mathematical equation as mentioned below:
1 Pound = 0.45359237 Kilogram
While 1 Kilogram = 2.2046226218 Pounds
The values might appear somewhat daunting to remember, but we suggest you keep the relationship between LBS and KG in minds if conversion is your regular deal.
How to Convert Pounds to Kg
Once you have known the relations between the units, it becomes easy to convert them. You can convert Pounds to KG in two ways- either using the formula or with the help of SquareYards’ lbs to kg Converter.
In the former method, simply multiply the value of Pounds by 0.45359237 and solve the equation. The resulting value would be in kilograms.
For the latter, use SquareYards’ Pounds to KG Converter. Enter the conversion value in the desired field and tap the convert button.
The Formula for Converting lbs to Kg
The conversion formula for Pounds to KG can be expressed mathematically as follows:
Kilograms = Pounds x 0.45359237
Let us solve a few examples to have a better clarification of the conversion process of these measurement units of mass.
1 pound is equal to 0.45359237 kilograms. Therefore, to convert lbs to kg, you can multiply the number of pounds by 0.45359237.
Examples for Converting Pounds to Kilograms
Example 1: Convert 110 Pounds in KG
Sol: Putting the value of pound in the above formula, we will get-
KG = 110 x 0.45359237 = 49.89516070.
So, 110 pounds in KG is equivalent to 49.89516070 units.
Example 2: Convert 145 Pounds in KG
Sol: Following the same process as above, we will get-
KG = 145 x 0.45359237 = 65.77089365.
Hence, 145 pounds amount to 65.77089365 kilograms.
Example 3: Convert 400 Pounds in KG
Sol: Putting the value of pounds in the conversion formula, we will get-
KG = 400 x 0.45359237 = 181.43694800.
Therefore, 400 pounds is equivalent to 181.43694800 KG.
Example 4: Convert 130 Pounds in KG
Sol: KG = 130 x 0.45359237 = 58.96700810.
Thus, 130 pounds convert to 58.96700810 kilograms.
Example 5: Convert 500 Pounds into KG
Sol: KG = 500 x 0.45359237 = 226.79618500.
Hence, 500 pounds is equivalent to 226.79618500 kilograms.
Similarly, you can convert 125 pounds in KG, 165 pounds in KG, 493 pounds in KG, 185 pounds in KG or literally, any value of LBS into kilograms.
