When you stand on level ground, the normal force is equal to your weight.

Here's why:

* Weight is the force of gravity acting on your mass.

* Normal force is the force exerted by a surface perpendicular to the object in contact with it.

When you stand on level ground, your weight pulls you downwards. To counteract this force, the ground pushes back on you with an equal and opposite force – the normal force. This keeps you from sinking into the ground.
