Percentage Error Solution

STEP 0: Pre-Calculation Summary

Formula Used

Percentage Error = (Erroneous Quantity-True Value)/True Value
%E = (Q_err-X_E)/X_E
This formula uses 3 Variables

Variables Used

Percentage Error - Percentage Error is a measure of how inaccurate a measurement is, standardized to how large the measurement is.
Erroneous Quantity - Erroneous Quantity is defined as limiting error, specified quantity is taken as true quantity, and maximum deviation quantity is known as the incorrect or erroneous quantity.
True Value - True Value refers to the exact or correct value of a quantity that is generally agreed upon by the scientific community or determined through highly accurate methods.

STEP 1: Convert Input(s) to Base Unit

Erroneous Quantity: 10 --> No Conversion Required
True Value: 4 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

%E = (Q_err-X_E)/X_E --> (10-4)/4

Evaluating ... ...

%E = 1.5

STEP 3: Convert Result to Output's Unit

1.5 --> No Conversion Required

FINAL ANSWER

1.5 <-- Percentage Error

Absolute Static Error of Quantity

Go Absolute Value = True Value*Relative Static Error

Measured Value of quantity

Go Measured Value Output = Absolute Value+True Value

True Value of Quantity

Go True Value = Absolute Value/Relative Static Error

Relative Static Error

Go Relative Static Error = Absolute Value/True Value

Percentage Error Formula

Percentage Error = (Erroneous Quantity-True Value)/True Value
%E = (Q_err-X_E)/X_E

What is true value in error?

A true value, also called a true score, is a psychometric concept that refers to the measure that would have been observed on a construct were there not any error involved in its measurement. The concept of a true value relates to the concepts of reliability and validity.

How to Calculate Percentage Error?

Percentage Error calculator uses Percentage Error = (Erroneous Quantity-True Value)/True Value to calculate the Percentage Error, The Percentage Error formula is defined as a measure used to quantify the accuracy of a measurement by comparing it to the true or accepted value. It represents the error as a percentage of the true value. Percentage Error is denoted by %E symbol.

How to calculate Percentage Error using this online calculator? To use this online calculator for Percentage Error, enter Erroneous Quantity (Q_err) & True Value (X_E) and hit the calculate button. Here is how the Percentage Error calculation can be explained with given input values -> 1.5 = (10-4)/4.

FAQ

What is Percentage Error?

The Percentage Error formula is defined as a measure used to quantify the accuracy of a measurement by comparing it to the true or accepted value. It represents the error as a percentage of the true value and is represented as %E = (Q_err-X_E)/X_E or Percentage Error = (Erroneous Quantity-True Value)/True Value. Erroneous Quantity is defined as limiting error, specified quantity is taken as true quantity, and maximum deviation quantity is known as the incorrect or erroneous quantity & True Value refers to the exact or correct value of a quantity that is generally agreed upon by the scientific community or determined through highly accurate methods.

How to calculate Percentage Error?

The Percentage Error formula is defined as a measure used to quantify the accuracy of a measurement by comparing it to the true or accepted value. It represents the error as a percentage of the true value is calculated using Percentage Error = (Erroneous Quantity-True Value)/True Value. To calculate Percentage Error, you need Erroneous Quantity (Q_err) & True Value (X_E). With our tool, you need to enter the respective value for Erroneous Quantity & True Value and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
