Weight measurements refer to the quantification of how heavy an object is. This is typically expressed in units such as grams, kilograms, pounds, or ounces. Different systems of measurement are used around the world, with the metric system being common in many countries, while the imperial system is often used in the United States. To measure weight, various tools can be employed, including scales and balances. Scales provide a direct reading of weight, while balances compare the weight of an object to known weights. Accurate weight measurements are essential in fields like science, medicine, and cooking.
