Approximately how many inches is a 60 mm sieve?

1.5 inches
2.0 inches
2.5 inches
3.0 inches

The correct answer is: 2.5 inches

The correct conversion of millimeters to inches is essential for interpreting sieve sizes accurately. A sieve size of 60 mm is converted to inches using the conversion factor where 1 inch is approximately equal to 25.4 mm. To make this conversion, divide the millimeter measurement by 25.4. In this case, 60 mm divided by 25.4 mm/inch equals approximately 2.36 inches. This result aligns closely with the answer choice of 2.5 inches as the closest approximation. Using this method ensures that you have a solid understanding of how to convert between metric and imperial measurements, which is critical in various fields, including lead assessment where material sizing is crucial for testing and regulation.
