How is the ideal weight of 67.3 kg for 171.5 cm calculated?

By the Devine formula (1974): it starts from 50 kg for a man and adds 2.3 kg for every inch above 5 feet. 171.5 cm ≈ 67.52 inches, 7.52 of them above the 60-inch mark: 50 + 2.3 × 7.52 ≈ 67.3 kg. Below 5 feet (152.4 cm) this calculator sets the surcharge to zero and keeps the base weight.

Why do the ideal weight and the healthy range give different answers?

They are two different models. The range 54.4 kg - 73.5 kg is the band 18.5 ≤ BMI < 25 applied to 171.5 cm, while the ideal weight 67.3 kg is a single point from the Devine formula and corresponds to a BMI of 22.88. The formula knows nothing about age, frame size or muscle, so its point need not sit in the middle of the range.
