Why does a person weigh different at different places on our planet?

The reason, plain and simple, is that the Earth bulges slightly at the Equator and all places there are nearly 13 kilometers farther away from the planet’s center, i.e. center of its gravity. As you move away from it, the force of gravity is reduced in inverse proportion. A 75 kilogram person living in London would weigh 250 grams less in Singapore.
