How this is calculated

Energy burn is estimated from metabolic equivalents (METs): light office work seated is about 1.3 MET, standing light work about 1.8 MET. Hourly burn is MET × body-mass(kg) × 1.05. The difference is the extra you spend by standing instead of sitting.

Reality check: a standing desk is a posture and movement tool, not a weight-loss device. The extra 63 kcal/hour is real but modest — the bigger wins are less prolonged sitting, better circulation, and an easier path to staying upright.
