health.muscle-mass Calculator
Estimates skeletal muscle mass from height and weight using prediction equations, and calculates appendicular skeletal muscle index (ASMI) for sarcopenia screening. ASMI below 7.0 kg/m² (men) or 5.5 kg/m² (women) meets the diagnostic threshold for sarcopenia.
Inputs
Wt
Body or object weight. For health calculators, usually in kg or lbs.
Height
Vertical measurement. For health calculators, typically standing height without shoes.
Age
Age in completed years. Many health and fitness formulas adjust for age.
Sex
Reference formula or conversion factor shown for context.
Results
skeletal muscle mass (kg)
The computed mass of the object or substance.
SMM % of body weight
The computed weight (gravitational force) or mass.
ideal range
The difference between the maximum and minimum values.
sarcopenia threshold
Sample size or count used in the calculation.
status
Current state of the system, process, or metric — typically pass/fail, healthy/warning/critical, or a descriptive classification.
