Estimating the total number of grains of sand in the world is challenging, but scientists suggest there are roughly 7.5 x 10^18 grains, or 7.5 quintillion. This estimate considers all the beaches, deserts, and riverbeds on Earth. However, the number can vary significantly depending on factors like erosion and sediment deposition. Ultimately, while the figure provides a ballpark estimate, the exact number remains unknown.
