The #5 values follow the FHWA reference table. Metric values are direct conversions, not a local reinforcement standard. Confirm the bar standard, grade, coating, and supplier data before ordering or detailing reinforcement.
Look up the nominal diameter, unit weight, and cross-sectional area for U.S. #5 rebar, commonly called 5/8-inch rebar.
Use this #5 rebar reference
- Use this page when a U.S. drawing, quote, or material list specifies #5 or 5/8-inch rebar.
- Use the unit weight to check a takeoff or convert a known bar length into mass; it does not choose reinforcement size, spacing, or cover.
- 20 × 20 normally describes mesh spacing, not a #5 bar. Treat welded-wire mesh as a separate product and specification.
