How the dimensions were calculated
The H-4 Hercules is 66.65 metres long, 97.51 metres across and 24.18 metres high in the sourced aircraft record. We convert each figure to centimetres, then divide it by 400. Nothing is inferred from a retailer's box photograph.
66.65 m × 100 ÷ 400 = 16.7 cm model length
