With a height of 170 centimeters, the standard weight is generally considered to be 65 kilograms. Standard weight is an indicator designed to assess the weight pattern of an adult, and is usually easiest to calculate in kilograms by subtracting 105 from the height in centimeters. So 170 centimeters minus 105 is 65 kilograms. It is usually considered that 10% over the standard weight is considered overweight and 20% over is considered obese. It is important to note that this approach is usually only suitable for adults and is not appropriate for children, the elderly or special populations. In addition to the standardized weight, the body mass index (weight divided by height squared) is more commonly used for weight estimation. It is recommended that people with abnormal weight should seek medical attention.
