What is the relationship between kilograms and newtons?

[TyroneBorr]

I’m trying to understand how kilograms (a unit of mass) relate to newtons (a unit of force). Can someone explain how they are connected?

Kilograms (kg) and newtons (N) measure different physical quantities, but they are related through Newton’s Second Law of Motion:
F=m⋅aF = m \cdot aF=m⋅a

• kg measures mass.
• N measures force.
• On Earth, the acceleration due to gravity is approximately 9.8 m/s²9.8 \, \text{m/s²}9.8m/s².

So, the weight of a 1 kg object (force due to gravity) is:
F=1 kg×9.8 m/s²=9.8 NF = 1 \, \text{kg} \times 9.8 \, \text{m/s²} = 9.8 \, \text{N}F=1kg×9.8m/s²=9.8N
In short: Mass in kilograms × gravity (9.8 m/s²) = weight in newtons.
