The number of grains of sand in a 30-minute hourglass can vary widely depending on the size of the grains and the design of the hourglass. However, a typical hourglass might contain anywhere from several hundred to several thousand grains of sand. For example, a standard hourglass might hold around 1,000 to 2,000 grains of sand to measure the 30-minute duration. Ultimately, the exact number would depend on specific measurements of the hourglass used.
