墙面乳胶漆用量与涂刷面积计算器
根据墙面可涂刷面积、涂刷遍数与涂料每升涂布率，精准估算装修所需的乳胶漆总升数或桶数。
Total gallons (or liters) of paint needed
Total wall area minus doors and windows
Number of coats applied (2 coats standard for full hide)
350–400 ft²/gal (or 10 m²/L) on smooth primed drywall
分步代入计算过程
Required architectural paint volume G equals net paintable wall surface area A multiplied by the number of finish coats C, divided by the single-coat spread coverage rate S_cov.
常见参考标准值
9.8 – 11.2 m² per Liter metric equivalent
Porous substrates absorb 30%–40% more first-coat binder
Subtract openings from perimeter × ceiling height
