Health level can also be quantified as: 1. Drinking water formula: the daily drinking water required by adults = body weight (kg) ×30~40 (ml). For children over 2 years old, daily water requirement = body weight (kg) ×80~90 (ml). For children under 2 years old, daily water requirement = body weight (kg) × 100~ 150 (ml).
2.BMD formula: BMD = (weight (kg)- age) ×0.2. If the result is less than -4, the risk is high.
3. Body fat rate formula: female body fat rate formula: parameter a= waist circumference (cm) × 0.74; Parameter b= weight (kg) × 0.082+34.89; Body fat rate =(a-b)÷ body weight × 100%. When calculating the percentage of male body fat, the parameter b= body weight (kg) ×0.082+44.74.
4. Happiness formula: personal happiness = desire for material consumption.
