Question

1kgwt is equal to:
A. 9.8N
B. 980N
C. 98N
D. None of these

Answer 1

Hint: However, the scientific and more broad "unit" of calculating all of forces is the unit newton. One kilogram-weight (the force, not the mass denoted by simply kilogram) equals 9.8 N. We can calculate the weight of an object by multiplying mass 1 kg with acceleration $1m{s}^{-2}$ which can be known as 1kgwt.

Complete answer:
Kilogram weight is a force First of all, kilogram is a term that actually denotes "mass." Mass is a constant. It's the same everywhere.
So, someone needs to have an accurate description of what is one kilogram, right? There's an International Prototype Kilogram exactly for that purpose. It weighs exactly one kilogram. Or rather, whatever it weighs is believed to be one kilogram.
Now, weight is a force. It is equal to the mass of the object multiplied by the acceleration due to gravity (which is 9.8 metres per second squared). Weight, thus, depends on the body on which it is. For example, on earth, something that weighs 60kg will weigh only 6kg only on the moon, because the value of the variable "acceleration due to gravity" changes from body to body (gravitation in its turn is based on mass too).
Multiplying that acceleration to the constant "mass," we can calculate the weight of an object. The weight is actually a kind of force that humans popularised because of daily needs. No one loves saying "Give me 10 newton of sugar."
Kilogram weight is a force. It equals the mass multiplied by acceleration due to gravity (which is $9.8m{s}^{-2}$). So now,
$1newton=1\times 9.8m{s}^{-2}$
 = 9.8 metres per second squared
That's how it's related to kilogram-weight.

So, the correct answer is “Option A”.

Note:
However, the scientific and more relevant "unit" of calculating all of forces is the unit newton. One kilogram-weight (the force, not the mass denoted by simply kilogram) equals 9.8 N.
So now,
$1newton=1\times 9.8m{s}^{-2}$
 = 9.8 metres per second squared
That's how it's related to kilogram-weight.
