精度越高量程越小：0.001g精度秤量程通常≤50g，0.01g精度秤可达200-500g，需称大件黄金则选0.01g/500g款而非追求0.001g

Unverified标称精度0.01g的珠宝/克拉秤，最大量程通常仅100-500g，量程越大精度越低，二者不可兼得88% similarUnverified0.1g高精度秤在满量程附近（如接近3kg）时精度会衰减，标注'0.1g精度'通常仅在500g以内准确，大量程与高精度不可兼得84% similarUnverified精度与量程通常互斥：0.1g高精度秤量程多在2-3kg，追求5kg大量程往往只能接受1g精度，无法两全需按主要用途取舍80% similarUnverified珠宝/黄金克重交易选0.01g精度（100g量程）即可满足；克拉钻石、药材配比需0.001g精度（含防风罩）80% similarUnverified精度与量程存在反向权衡：单一传感器难以兼顾大承重和高精度，高承重款（180kg+）通常精度只能到100g，追求1g级精度的秤往往量程被限制在5-10kg79% similar
