OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at https://www.osha.gov.

MEMORANDUM FOR: DAVID C. ZEIGLER, DIRECTOR
DIRECTORATE OF ADMINISTRATIVE PROGRAMS
ATTENTION: JIM RHODES, SENIOR MANAGEMENT ANALYST
FROM: ROGER A. CLARK, DIRECTOR DIRECTORATE OF COMPLIANCE PROGRAMS
SUBJECT: Annual Metric Conversion Report
In response to your memorandum of January 4, the following is a progress report of the significant milestones, accomplishments, and problems associated with Task 5 of the Annual Metric Conversion Report.
(1) The use of metric units as the preferred units of measurement in written reports is proceeding well, however, the use of metric units during oral presentations is often successful only when accompanying written or slide materials are used that serve as reminders of the preferred terms. In addition, spontaneous replies to questions often involve the use of the more familiar english measurement units.
Successful use of metric in all presentations still remains a matter of changing habits.
(2) Complete conversion to metric is contingent on acceptance by the specific industry involved. For example, the use of english units is still very common in the construction industry. Most components such as doors, wires, pipes, and lumber are manufactured using english units. There is some industry movement towards the use of metric units and our efforts will keep pace in order to assure good communication. With respect to compliance matters, the use of metric will be paced by related changes in the publication of new or revised safety and health standards, and by directives incorporating or referencing national consensus standards.
