The weight of anything/article is the force of gravity currently applied to that object. Weight and mass are different because, while the mass of a thing/article remains the same no matter where the thing/article t is present, the weight will vary depending on its location, gravity, and most significantly, the amount of gravity in that area.
Let us now understand the difference between Kilo and Lbs.
In “Metric System”, there are essentially two dissimilar systems. The International measurement (SI System) uses meters, kilograms, and seconds in length, weight, and time. It is sometimes called the MKS system. Another system that uses centimeters (cm), grams (g), and seconds (s) for length, mass & time is called the Gaussian system or Electrostatic system, the “cgs System”, and is sometimes called the.
Each system has its own set of units available for power, power, electricity meanwhile, etc. Surprisingly, there are significant differences in the basic equations of electrodynamics depending on what system do you use
Mass can be measured using both Pounds (lb) and Kilograms(kgs). The pound mentions the imperial system of weight and mass. Kilogram, on the other hand, was adopted under the SI system of units in 1959. There is a growing difference when calculating mass in kg as opposed to the same calculation in pounds.
Pound Mass and Pounds Force one of the major sources of confusion in the Imperial measurement system is that both mass & force are measured using the same unit, the pound. To distinguish between the two, one is called Pound-Mass (LBM), and the other is Pound-Force (lbs).

A kilogram (symbol: kg) is the basic SI unit of mass. A gram is defined as a 1/1000th of kilogram pounds. Unit conversion refers to units of equal mass in other systems. In this measurement of SI system, a kilogram (kg) is measured as equal to the mass of 1 liter of water which is protected and stored in a safe place at the International Bureau at France of Weights & Measures; IPK is a typical Iridium-Platinum(Ir-Pt) cylindrical tube that is precisely equal to one kg. To know the relation between pound and kg, we shall also need to learn more about a pound.
A pound (abbreviation: lb) is a unit of weight or weight in many different systems, including English units, Imperial units, and customary in the United States. Its size may differ from one system to another system. The most widely used pound today is the international avoirdupois pound. The pound of international avoirdupois equals exactly 453,523,237 grams.
The definition of an international pound was agreed upon by the United States and the Commonwealth of Nations in 1958. In the United Kingdom, the use of the international pound was introduced in the Weights and Measures Act 1963. A pound of avoirdupois equals 16 avoirdupois ounces and exactly 7,000 grains
The mass of the object was told in “LBM”; we can convert the mass to “LBF” if we know the gravity because of acceleration; technically, it’s not a unit of conversion from mass to weight,
As per Newton’s 2nd law (force = mass × acceleration) to get weight lbm.ft/s2 and to convert weight from lbm.ft/s2tolbf by taking this equation 1 lbf=32.174 lbm.ft/s2.
When a person with a mass of 180 LBM on earth travels to the moon, he weighs 29.76 LBF.
- Pound to Kilogram
Pound is equal to precisely 0.45359237 kilograms by description i.e.1 lbm ≡ 0.45359237 kg. or one pound = 0.4536 kgs.
Rajanikanth weighs 192 lbs. what is the weight of Rajanikanth in kilograms?
- 68.0 kg
- 86.80 kg
- 98.09 kg
- 87.01 kg
- Ans. (d) 87.01 kg pound = 0.4536 kgs or 1 kg =2.204 lb
Wt. in kg = Wt. in lb x (01 kg / 2.2 lb)
a kilogram Wt. in Pounds is divide by 2.2:
x kg = 192lbs x 1 kg/2.2 lbs
x kg = 87.01 kg
and hence Rajanikanth weighs 87.01kgs.
- Kilogram to Pound
Since one pound is equal to 0.4536 kgs, if we revert the same then one kilogram is equal to how many pounds .e. 1 kg = 2.204 pounds(1kg=2.024 lb).
Rajani buys 10kilograms of mangoes. How many pounds of mangoes did he buy?
- 12.68 lb
- 29.68 lb
- 02.60 lb
Ans. (b) 22.04 kg; one kg = 2.204 pounds
= 10 x 2.24pounds
Rajani buys 5 pounds of bread. How many kg of bread did he buy?
- 2.268 kg
- 4.566 kg
- 8.98 kg
- 5.82 kg
Ans. (a) 2.268 kg pound = 0.4536 kgs
= 5 x 0.4536 pounds
Differences between Pound and Kilogram
The points are listed as follows
|1||A kilogram comes from a Greek word, where Kilo means a thousand.||The pound is derived from a German word.|
|2||A kilogram is from the metric unit||A pound is from the imperial unit|
|3||The kilogram is abbreviated as “kg.”||The pound is abbreviated as “lb.”|
|4||Most countries accept a kilogram as a unit of mass||Few countries USA and UK accept the pound as a unit of mass|
|5||1 kilogram = 2.204 pounds.||1pound = 0.453 kg.|
|6||The kilogram unit is used only to measure measurement mass.||The pound unit is used only to measure measurement force and mass.|
|7||The kilogram is not a currency||The pound is a currency for the United kingdom country.|
In this topic, we learned about introduction to the mass, metric system, SI System, cgs system, conversion from kilogram to pound, and pound to kilogram with examples.
Knowing how the two measurements relate to each other will help us harmonise the measurements, convey correct information and prevent any confusion.
