Basis: 1 inch = 25.4 mm exactly (international inch definition)
Rounding, fractions, and tolerance
The converted value 679.45 mm is exact. To one decimal it is 679.4 mm; the nearest 0.5 mm is 679.5 mm with 0.05 mm absolute error. A rounded metric size is not interchangeable unless that difference fits the tolerance budget.
A nearby rounded size is acceptable only when its absolute difference is within the documented dimensional tolerance and all non-dimensional compatibility checks pass.
Furniture fit check
An inch furniture dimension must be compared with a metric doorway or alcove survey. For this route, 26 3/4 inches converts to 679.45 mm. Convert component and opening dimensions, then calculate remaining clearance.
- Convert component and opening dimensions, then calculate remaining clearance.
- Turning path, handles, trim, and floor slope also affect access.
Illustrative measurement workflow; it does not claim that this value is a standard product size.
Editorial measurement check
If the value came from a drawing, carry its tolerance and revision context alongside the converted unit.
Compare the smallest permitted opening with the largest permitted component whenever clearance, rather than center value, controls the decision.
Retain one guard digit during calculation, then round once at the final communication or machine-entry step.
Nearby comparison and substitution boundary
Nearest-0.5-mm rounding maps exact results from 679.25 mm up to but not including 679.75 mm to 679.5 mm under half-up ties. A physical substitution changes this dimension by 0.05 mm; verify fit, thread, clearance, or process allowance as applicable.
Candidate: 679.5 mm; absolute difference: 0.05 mm.
