Estimating the number of grains of sand in the world is a challenging task due to the sheer variability in the size of sand grains and the vast number of beaches and deserts around the globe. Sand grains come in different sizes, ranging from very fine to coarse.

One attempt to estimate the number of grains of sand was made by Dr. Jason Marshall, a physicist. He estimated that there are roughly 7.5 x 10^18 (7.5 quintillion) grains of sand on Earth. However, it's important to note that this is a rough estimate and the actual number can vary significantly depending on the criteria used for the estimation.

The number of grains of sand is immense and serves to illustrate the vastness of Earth's geological features. Keep in mind that this is a speculative estimate, and accurately counting every grain of sand on Earth is practically impossible.
