The answer is: Spring scale
For adults, a person's ideal weight is determined by their body mass index (BMI). Body mass index is an index that shows the ratio of a person's height to his weight. A BMI calculator can help evaluate whether a person is a normal weight, overweight, or underweight. The BMI calculator is easy to use and helps determine a person's ideal weight based on their age and height. Knowing an individual's ideal weight can help them achieve and maintain a healthy lifestyle. In addition, it can also be used as a guide when setting weight loss goals. The best way to calculate your BMI and ideal weight is to use an online calculator or app that takes into account other factors such as gender and activity level.
