What is the role of Appendix B in terms of measurement?

Appendix B plays a crucial role in offering conversion factors for metric values, which is essential for ensuring that measurements are accurately understood and applied across different systems of measurement. This is particularly important in a jurisdiction like Ontario, where both imperial and metric measurements may be used in various construction processes and regulatory documents.

Providing these conversion factors prevents confusion and errors that could arise from misinterpreting measurements, especially when different trades or professionals are involved in a project. In a practical sense, this means that if a specification is given in metric, the appropriate conversion to imperial can be made easily, facilitating communication and adherence to the Ontario Building Code.

The other choices relate to different aspects of building codes and safety regulations but do not specifically address the importance of measurement conversion that Appendix B provides.
