This is the Devine formula for men: ideal weight (kg) = 50 + 2.3 × (height in inches − 60), where height in inches = cm ÷ 2.54. At 180 cm (≈ 70.9 in) that is 50 + 2.3 × 10.9 ≈ 75.0 kg. For women the base is 45.5 kg instead of 50. It is a clinical reference point, not a hard target.

Questions
What is the Devine formula?
A clinical estimate of ideal body weight: for men, 50 kg plus 2.3 kg for every inch of height over 5 feet (60 inches). At 180 cm it gives about 75 kg.
Is ideal weight a target I should hit?
Not strictly. It is a reference used in medicine (for example, for drug dosing). Healthy weight varies with build, muscle mass and body composition.
