Body Surface Area (m²) = 0.0061 × Height (cm) + 0.0128 × Weight (kg) - 0.1529

Caloric Supply for Burned Adults (kJ/d) = 4184 × Body Surface Area (m²) + 104.6 × Burn Area (%)

Compared to foreign formulas, this formula aligns with the energy consumption patterns of Chinese adults with burns. Calculating the basal caloric needs based on body surface area is more reasonable than using body weight.

Additionally, this formula can estimate energy consumption for different burn areas, increasing by 104.6 kJ for each additional 1% burn area. The calculated results are consistent with the trend of resting energy expenditure and slightly higher than resting energy expenditure values.
