How to Calculate Ideal Weight for 198cm
Convert height to inches
198 cm ÷ 2.54 = 78 inches (6'6")Inches above 5 feet (60 in)
78 − 60 = 18 inches above 5ftApply Devine formula (most used)
Men: 50 + (2.3 × 18) = 91.3 kgWomen: 45.5 + (2.3 × 18) = 86.8 kgVerify with BMI
BMI = 91.3 ÷ (1.98)² = 22.7 ✅ Within healthy rangeAbout the 4 Medical Formulas
Hamwi (1964)
The earliest formula, developed by Dr. G.J. Hamwi in 1964 for clinical nutrition. Published via the American Diabetes Association and became the first bedside reference.
Devine (1974)
Developed by Dr. B.J. Devine in 1974 for drug dosage calculations. Despite its pharmacological origin, it became the most cited IBW formula in electronic health records worldwide.
Robinson (1983)
Developed by Dr. J.D. Robinson in 1983 using regression analysis of Metropolitan Life Insurance data. Considered the most statistically rigorous of the four.
Miller (1983)
Developed by Dr. D.R. Miller in 1983 using updated Metropolitan Life tables. Typically produces the highest values, accommodating heavier body frames.
Why Does Ideal Weight Differ Between Men and Women?
At 198cm, men's ideal weight is approximately 6.6 kg higher than women's. The primary reason: men naturally carry higher muscle mass (muscle is denser than fat at equal volume) and higher bone density. Per PMC research (2021), healthy body fat is 20–25% for women vs 15–20% for men.
