This app is using to converting amounts from Slug to Newton as well as converting amounts from Newton to Slug.
First of all, let us talk about Newton type and Slug type:
Slug (sl):
The slug is a derived unit of mass in the weight-based system of measures, most notably within the British Imperial measurement system and in the United States customary measures system.
Systems of measure either define mass and derive force or define a base force and derive a mass unit.
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 Slug to Nweton and vise verse.
So let's start using that.
