How is percent accuracy calculated in relation to kWh registration?

Percent accuracy in relation to kWh registration is calculated by examining the relationship between the kWh measured by the meter and the kWh as measured by a standard reference. This method allows for determining how closely the meter's readings align with a known, accurate standard.

The calculation (kWh measured by meter divided by kWh as measured by standard) multiplied by 100 expresses this relation as a percentage. A result of 100% would indicate that the meter is perfectly accurate, while a value above or below that would show the degree of inaccuracies present in the meter’s readings compared to the standard. This metric is crucial in ensuring that utility measurements are reliable and provide consumers with accurate billing.

The other options do not correctly reflect the standard method for calculating percent accuracy. Each of those alternatives either misrepresents the elements involved in the comparison or changes the basis of calculation in a way that does not align with the concept of determining accuracy against a standard measure.
