What unit is typically used to express the error in tape measurement due to temperature?

Answer: C — Inches

The unit commonly used to express the error in tape measurement due to temperature is inches. When measuring distances, materials can expand or contract with temperature changes, which affects the accuracy of measurements. Tapes are often calibrated at a specific temperature, typically at 68°F (or 20°C). When the temperature deviates from this calibration, the length of the tape can effectively change, leading to measurement errors. Inch is an appropriate unit because it directly relates to standard measurements in construction and surveying. The use of inches allows for a more precise quantification of any discrepancies caused by temperature variations, enabling inspectors to adjust their measurements accordingly to ensure accuracy in their work.
