实验相对误差百分比计算器
利用 PE = ((E - T) / T) × 100 计算带正负号的百分比误差、实验测量值 E 或理论真实值 T。
Relative error in percent (+ overestimate, - underestimate)
Observed lab or sensor reading
Accepted reference standard value
分步代入计算过程
Percent Error quantifies measurement accuracy by expressing the deviation between an experimental value E and an accepted theoretical value T as a percentage of the true value: PE = ((E - T) / T) × 100.
常见参考标准值
