Percent Error Table: Percent error by Measured / experimental value

Reference table of percent error for Percent Error across a range of measured / experimental value values — exact, engine-computed figures you can read off at a glance.

How to use this table

Find the row closest to your measured / experimental value and read across to the percent error. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Percent Error Calculator for a precise answer.

Need a value that is not in the table? — the Percent Error Calculator does it instantly, for free, with the formula and a worked example built in.

Frequently asked questions

Each cell is computed with the standard formula using exact arithmetic — the same calculation behind our Percent Error Calculator — so every figure is accurate for the stated assumptions.

Yes. The table covers common measured / experimental value values; for any exact figure, enter your own numbers in the Percent Error Calculator.
