This app is using to convert amounts from Kilogram to Newton as well as converting amounts from Newton to Kilogram.

First of all, let us talk about Kilogram type and Newton type:

Kilogram (kg):

The SI unit of mass, equivalent to the international standard kept at Sèvres near Paris (approximately 2.205 lb).
The kilogram or kilogramme is the base unit of mass in the International System of Units. Until 20 May 2019, it remains defined by a platinum alloy cylinder, the International Prototype Kilogram, manufactured in 1889, and carefully stored in Saint-Cloud, a suburb of Paris.


Newton (n):

The newton (symbol: N) is the International System of Units (SI) derived unit of force. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically Newton's second law of motion.
The unit of measurement for weight is that of force, which in the International System of Units (SI) is the newton.


By the way, As far as I told, This app is useful for converting amounts from Kilogramt to Newton and vise verse.
So let's start download and using that.
