How do you convert kilograms (kg) to newtons (N)?

You don't convert kilograms to newtons. By the time you've heard of these units, you know that 'kilogram' is a unit of mass, 'newton' is a unit of force or weight, and that mass and weight are different things.
Mass and force are related by Newton's second law:
Force = Mass x acceleration .
From this simple formula, you can see that in order to relate a mass to a force, you need to know an acceleration. And if the acceleration changes, then the relationship between the force and the mass also changes. So there's no direct conversion.
ON EARTH ONLY, one kilogram of mass weighs 9.8 newtons. The acceleration that connects them is the acceleration of gravity on Earth. In other places, with different gravitational accelerations, 1 kilogram weighs more or less newtons.
But they don't convert directly. That would be like asking "How do you convert miles to miles-per-hour ?"

To convert kilograms to Newtons, multiply the mass in kilograms by the acceleration due to gravity on Earth, which is approximately 9.8 m/s². For example, 5 kg converts to 49 Newtons since 5 kg multiplied by 9.8 m/s² equals 49 N.
To convert kilograms (kg) to Newtons (N), you must use the formula that relates mass to force under Earth's gravity. This is due to the fact that weight is a force, and it is measured in Newtons, while mass is a measure of the amount of matter in an object and it is measured in kilograms.
1 N = 1 kg × 9.8 m/s², since the force of gravity on Earth accelerates objects at approximately 9.8 meters per second squared. To convert your mass in kilograms to weight in Newtons, you simply multiply the mass by 9.8.
For example, if you have a mass of 5 kilograms, the weight in Newtons is:

Weight (N) = Mass (kg) ×9.8 m/s²
Weight (N) = 5 kg × 9.8 m/s²
Weight (N) = 49 N

The relationship between mass and weight is crucial to understand, especially since the concept of weight varies depending on the gravitational pull, whereas mass remains constant.

To convert kilograms to newtons, multiply the mass in kilograms by the acceleration due to gravity (9.8 m/s² on Earth). This gives you the weight in newtons, as force and mass are related through the equation F = m × a. Remember that kilograms measure mass, while newtons measure force, so they cannot be directly converted without considering gravity.
