Question

how are the units of weight, kgf and newton related

Answer 1

kilogram force is a force measurement unit.The kilogram force is a metric unit of force(kgf).The kilogram force is equal to mass of one kilogram multiplied by the standard acceleration due to gravity on earth,which is defined as exactly 9.80665 meter per second.

Answer 2

Hi.

Here is your answer-----

__________________________

The kgf and the newton are related as---
   
               1 kgf = 9.8 N

 Proof---
 
  1 kgf = mass of 1 kg × acceleration due to gravity (g) m/s^2
     1 kgf  = 1 kg × 9.8 ms^-2
       1 kgf  = 9.8 m/s^-2
                                                             Hence Proved.
