health.pregnancy-weight-gain Calculator
Calculates recommended gestational weight gain by trimester based on pre-pregnancy BMI per IOM guidelines. Women with normal pre-pregnancy BMI should gain 11–16 kg total; obese women 5–9 kg — both insufficient and excessive gain increase obstetric risk.
Inputs
Pre Bmi
Body Mass Index = weight (kg) divided by height squared (m²). Below 18.5: underweight · 18.5–24.9: normal · 25–29.9: overweight · 30+: obese.
Current Weight Gain
Rate of charge flow (A). I = V/R. Above ~100 mA through the body can be lethal. Fuses protect against overcurrent.
Weeks
Weeks of pregnancy elapsed. Full term is 40 weeks from LMP. Below 37 weeks = preterm.
Twin
Reference formula or conversion factor shown for context.
Results
weight gained (kg)
The computed weight (gravitational force) or mass.
recommended total range (kg)
The combined total across all inputs and components.
status
Current state of the system, process, or metric — typically pass/fail, healthy/warning/critical, or a descriptive classification.
rate (kg/week, 2nd-3rd tri)
The value at the specified point or condition.
target rate
The value at the specified point or condition.
BMI category
The classification bucket this result falls into based on the computed value and the applicable reference scale.
