Verified route guide
Exact answer, measurement guidance, and nearby sizes
Direct answer and formula
1/32 inches is 0.79375 mm exactly because the international inch is exactly 25.4 mm.
1/32 × 25.4 = 0.79375 mm
Basis: 1 inch = 25.4 mm exactly (international inch definition)
Rounding, fractions, and tolerance
The converted value 0.79375 mm is exact. To one decimal it is 0.8 mm; the nearest 0.5 mm is 1 mm (difference 0.20625 mm), and the nearest whole millimeter is 1 mm (difference 0.20625 mm). Rounded metric sizes are 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.
Fractional shop layout
A fractional-inch layout mark is being transferred to a metric rule or digital caliper. For this route, 1/32 inches converts to 0.79375 mm. Use the exact metric value as the master reference and label any rounded field mark clearly.
- Use the exact metric value as the master reference and label any rounded field mark clearly.
- Rule graduation and pencil-line width limit practical placement.

Editorial measurement check
When dimensions form a chain, convert from the governing baseline instead of accumulating independently rounded segments.
A nearby catalog or tool size is only a candidate for review; numerical proximity does not establish interchangeability.
Verify the final setting with the instrument or template used in the real workflow before releasing the dimension.
Nearby comparison and substitution boundary
Nearest-0.5-mm rounding maps exact results from 0.75 mm up to (but not including) 1.25 mm to 1 mm with half-up ties. Using 1 mm as a physical substitute changes this dimension by 0.20625 mm; verify fit, thread, clearance, or process allowance as applicable.
Candidate: 1 mm; absolute difference: 0.20625 mm.
