Is the Richter Scale accurate or inaccurate?
The accuracy has never been challenged and why would it, what is the purpose of challenging the accuracy of Richter scale readings. .
Its accurate for what it does. That said, its made up so the results are arbitrary.
a scale is neither accurate or inaccurate. It is the readings/measuements taken that are accurate or inaccurate. Asking if a scale is accurate is asking if a ruler is accurate.
