Body Weight Unit Converter

Body weight is the total mass of your body, typically measured in kilograms or pounds. It reflects the combined weight of your bones, muscles, organs, fat, water, and other tissues.

Tracking body weight over time is one of the most common and accessible ways to monitor overall health. Significant or unexplained changes in weight can signal underlying medical conditions, nutritional imbalances, or shifts in physical activity.

Body weight is often interpreted alongside body mass index (BMI), waist circumference, and body composition measurements to give a more complete picture of health status.

Body weight is determined by the balance between energy intake (food and drink) and energy expenditure (basal metabolism, physical activity, and the thermic effect of food). Genetic factors account for roughly 30 to 50 percent of the variation in body weight between individuals.
