You weigh less at the Equator

The reason for this is that Earth bulges outward at the Equator because of the planet's rotation and its tendency to stay in a straight line while moving. This creates a gravitational field that is uneven, with more pull on the poles than in the middle. Because of this bulge, a person standing at the Equator is really further from the majority of Earth's mass than a person standing at either of the poles. But don't get your hopes up too much - the weight difference is a mere 0.5%! That's less than a pound for anyone weighing less than 200 pounds.
