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。

G = (A × C) / S_cov
选择要计算的未知量(或直接在任意输入框中输入数值):当前求解: G (gal or L) — Paint Volume Required
计算结果

分步代入计算过程

01Canonical Law: G = (A × C) / S_cov
02Given Inputs (Base Units): A (ft² or m²) = 400, C (coats) = 2, S_cov = 350
03Solve for G (gal or L) (Paint Volume Required): G (gal or L) = 2.2857

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.
