health.pediatric-bmi-percentile Calculator
Calculates paediatric BMI percentile for children aged 2–20 using CDC growth curves, classifying underweight, healthy, overweight, and obese. For children, BMI must be plotted on age-sex specific growth charts — the adult BMI thresholds do not apply.
Inputs
Age Months
Age in completed years. Many health and fitness formulas adjust for age.
Weight Kg
Body or object weight. For health calculators, usually in kg or lbs.
Height Cm
Vertical measurement. For health calculators, typically standing height without shoes.
Sex
Reference formula or conversion factor shown for context.
Results
BMI
BMI (body mass index) = weight (kg) / height squared (m^2). Under 18.5: underweight. 18.5-24.9: normal. 25-29.9: overweight. 30+: obese. Does not distinguish muscle from fat.
weight status
Current state of the system, process, or metric — typically pass/fail, healthy/warning/critical, or a descriptive classification.
P85 threshold (age
Reference formula or conversion factor shown for context.
P95 threshold
95th percentile latency -- 95% of requests complete faster than this. The standard SLA benchmark for web services.
height
The computed height.
