What is the normal/healthy weight range for 171.5 cm female?

The normal/healthy weight range for 171.5 cm female is 54.4 kg - 73.5 kg.

How is the ideal weight of 62.8 kg for 171.5 cm calculated?

By the Devine formula (1974): it starts from 45.5 kg for a woman 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: 45.5 + 2.3 × 7.52 ≈ 62.8 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 62.8 kg is a single point from the Devine formula and corresponds to a BMI of 21.35. The formula knows nothing about age, frame size or muscle, so its point need not sit in the middle of the range.
