Important Notes
Body fat calculators provide estimates, not precise measurements
DEXA scan, hydrostatic weighing offer more accurate results
Muscle mass affects calculations - athletes may have different ranges
Age, genetics, and hydration levels can affect measurements
Focus on trends over time rather than single measurements
Consult healthcare providers for medical advice
