Percent Error Calculator – Quickly find the accuracy of experimental results compared to true values. Ideal for science labs, research, and error analysis.
The Percent Error Calculator helps you compare an experimental (measured) value with a theoretical (true/accepted) value. It shows how accurate or precise a result is, making it essential for science, engineering, and data analysis.
✅ Percent error between experimental and theoretical values
✅ Accuracy of lab results and experiments
✅ Useful in physics, chemistry, and engineering
Simple input (experimental value + true value)
Instant percent error calculation
Works for positive and negative differences
Step-by-step explanation
📌 Students in science & math labs
📌 Teachers & tutors explaining accuracy concepts
📌 Researchers testing data against standards
📌 Engineers checking design accuracy
Percent Error is calculated as:
Percent Error=∣Experimental – Theoretical∣∣Theoretical∣×100\text{Percent Error} = \frac{|\text{Experimental – Theoretical}|}{|\text{Theoretical}|} × 100Percent Error=∣Theoretical∣∣Experimental – Theoretical∣×100
