The "G" at the top of Mount Everest refers to the acceleration due to gravity, and it is slightly lower than the global average. While the standard "G" at sea level is approximately 9.80665 m/s2, at the summit of Everest (8,848 meters), it drops to roughly 9.773 m/s2. This 0.3% decrease occurs because you are further away from the Earth's center of mass, and gravity follows an inverse-square law (g∝1/r2). Interestingly, you would actually weigh about 0.3% less at the summit than you do at the beach. However, this effect is partially countered by the fact that the Earth is not a perfect sphere; the "Equatorial Bulge" means that someone at the summit of Mount Chimborazo in Ecuador (which is closer to the equator) actually experiences even less gravity and is technically further from the Earth's center than someone on Everest. For scientists and mountaineers in 2026, these minute "G" fluctuations are critical for calibrating high-altitude research equipment and GPS sensors.
