How much weight in 5 kilograms?

Answer 1

Since kilograms is a measure of mass and weight is a force, we need to use the relation F=MA to determine the amount of weight exerted by 5 kg of mass. On Earth, gravitational accleration is roughly constant because most points on the surface are about the same distance from the Earth's center of gravity (The earth is a sphere). This acceleration is approximately 9.8 m/s². Multiplying mass (5 kg) and acceleration (9.8 m/s²), we get 9.8*5=49, and our units are kg*m/s², also known as Newtons (N), which is the metric unit of weight. Answer: 49 N
