The value 0.01 in. (0.254 mm) is given for a measurement. What two units are shown?

• A. Inches and Millimeters
• B. Inches and Centimeters
• C. Millimeters and Centimeters
• D. Inches only

Answer: (A)

When a measurement is shown with a value in one unit and its exact equivalent in another, it presents two units for the same dimension. Here, 0.01 in. is paired with 0.254 mm in parentheses, which is the metric equivalent of 0.01 inches. Therefore, the two units displayed are inches and millimeters. The mm label confirms the metric unit is millimeters (not centimeters), since 0.254 mm is used, not 0.254 cm. This format helps readers understand the size in either measurement system.
