Which of the following is a common measurement system used in woodworking?

The Imperial system is a common measurement system used in woodworking primarily in the United States and some other countries. This system includes measurements in inches, feet, yards, and fractions of an inch, all of which are practical for woodworking applications. Woodworkers often rely on these measurements for cutting, joining, and planning projects, as lumber and tools in the woodworking industry are typically designed around the Imperial measurements.

While the Decimal system is used in some contexts, such as for metric measurements, it is less common in traditional woodworking practices which have historically favored the Imperial system. The Binary and Hexadecimal systems, on the other hand, are used mostly in computing and electronics, making them unsuitable for woodworking measurement needs. Therefore, the Imperial system stands out as the standard for measuring and constructing in woodworking environments.
