What is the error when a line item lists 5 m and 500 cm as separate entries for the same length?

• A. Data entry error due to opposite units
• B. Data duplication
• C. Unit inconsistency; these are the same measurement.
• D. Rounding error

Answer: (C)

Unit consistency matters when recording lengths. 5 meters and 500 centimeters represent the same length because 1 meter equals 100 centimeters. Listing both as separate entries introduces inconsistent representation of the same quantity, which can lead to confusion, miscounting, or errors in later calculations. The proper fix is to standardize on one unit (for example, convert to 5 m or to 500 cm) and keep a single entry for that length. This isn’t a rounding error since the conversion is exact, and it isn’t simply data duplication in the sense of two distinct values meant to be different. The issue is that the same measurement is expressed in two different units, causing inconsistency.
