How do I convert from kg to Newtons?

You cant. kg is mass, newtons is force.

If a mass is in a gravity field, then

force= mass*g where g the graviational field constant is in newtons/kg (or m/s^2)

To convert from kilograms (kg) to Newtons (N), you will need to use the formula:

force = mass × gravitational field constant

The gravitational field constant is denoted as "g" and is measured in newtons per kilogram (N/kg) or meters per second squared (m/s^2).

First, determine the mass you want to convert from kilograms. Let's say the mass is 10 kg.

Next, find the gravitational field constant. On Earth, the average value for the gravitational field constant is approximately 9.80665 m/s^2.

Now, multiply the mass by the gravitational field constant:

force = 10 kg × 9.80665 m/s^2 ≈ 98.0665 N

Therefore, 10 kilograms is equivalent to approximately 98.0665 Newtons.

Remember that this conversion assumes the mass is located in a gravitational field, such as on Earth. If you are dealing with a different gravitational field, you would need to adjust the gravitational field constant accordingly.
