How can you calculate your weight on earth?

To calculate your weight on Earth, you can use the formula: Weight = Mass × Gravitational Acceleration. Your mass is typically measured in kilograms, while the gravitational acceleration on Earth is approximately 9.81 m/s². For example, if your mass is 70 kg, your weight would be 70 kg × 9.81 m/s², resulting in approximately 686.7 newtons. To convert this to pounds, you can multiply by 0.225, giving you around 154.3 pounds.
