When these tools help
Choose BMI for a quick screening ratio based on height and weight. Choose the weight-range calculator when you want to see the range produced by standard BMI reference values rather than focus on one score. Choose the Army Fitness Test calculator for event-by-event planning estimates for that particular test, not for a general measure of health or fitness.
BMI does not directly measure body fat, muscle mass, fat distribution, fitness, pregnancy, or individual health risk. Its categories can be less informative for athletes, older adults, children, and some populations. None of these tools diagnoses a condition, recommends treatment, or replaces advice from a qualified healthcare professional. Army fitness results are unofficial planning estimates and should be checked against current official standards.
All entered measurements and calculated results stay in your browser and are not sent to analytics. That privacy boundary does not make the outputs clinical: use them to understand the calculation and prepare questions, not to make a medical decision on their own.
