# 积载因数计算器

SF = 体积 ÷ 吨——把木材货物与 IMO 参考区间对照。

输入木材货物的总体积和总质量，计算器返回以 m³/t 计的积载因数，并标出你的货物落在 IMO CSS Code 中哪些木材货物（锯材、热带原木、胶合板、平板包装家具）参考区间内。

## FAQ

什么是积载因数？

积载因数（SF）是一公吨货物所占的立方米体积：SF = 总 m³ ÷ 总吨。新鲜热带硬木原木的积载因数通常为 1.3–2.8 m³/t，方端锯材为 1.8–3.4 m³/t。

积载因数对木材运输为什么重要？

船公司和租船人按吨计运费，却按体积装货。SF 高的货物在达到载重上限之前就装满了货舱，等于为未用足的舱容付费。把你的 SF 与 IMO 参考区间对照，即可判断货物对该类型是否典型。

积载因数怎么换算成货物密度？

货物密度（kg/m³）就是 1000 ÷ SF。积载因数 1.4 m³/t 约合 714 kg/m³——密度高到先触集装箱重量上限再装满体积（40 英尺高柜的平衡点约 390 kg/m³）。
