The World Health Organization provides guidelines on weight based on specific height measurements. For people who are 1.60, 1.70, or 1.80 meters tall, there are different ideal weight ranges. These calculations rely on the Body Mass Index, or BMI. This metric helps health professionals establish a reference range for adults. It calculates the upper and lower limits of weight for a person's stature. Staying within these limits can reduce the risk of chronic diseases. The system offers a general way to track physical health.
