How the converter decides
Each size is reduced to the centre of its published hip range (or the single hip value the brand gives). Your hip measurement — or the hip of the size you already wear — is compared with those centres.
If you are within 30% of the gap to the nearest size, you get that size. In the middle of the gap you see both sizes, because the choice then depends on the fit you want, not on the chart.
Waist is shown as a second opinion. In leggings the hip and seat decide whether the fabric stays opaque and stays up; a waist that points one size smaller usually just means a firmer waistband.
