Exact answer, measurement guidance, and nearby sizes
Direct answer and formula
32 mm is 1.2598425197 inches; the unrounded value is exactly 160/127 inch.
32 ÷ 25.4 = 1.2598425197 inches
Basis: 1 inch = 25.4 mm exactly (international inch definition)
Rounding, fractions, and tolerance
The factor 25.4 mm per inch is exact. A 4-decimal display is 1.2598 in. The nearest 1/64-inch mark is 1 17/64 in, differing by 0.146875 mm; the nearest 1/32-inch mark is 1 1/4 in, differing by 0.25 mm. Use a fraction only when its stated error is smaller than the allowed tolerance; otherwise retain the decimal.
A nearby rounded size is acceptable only when its absolute difference is within the documented dimensional tolerance and all non-dimensional compatibility checks pass.
Clearance-hole comparison
A measured hole or fastener clearance is listed in millimeters and needs comparison with inch tooling. For this route, 32 mm converts to 1.2598425197 inches. Compare actual diameters and the specified fit class; do not choose a tool solely from the nearest fraction.
- Compare actual diameters and the specified fit class; do not choose a tool solely from the nearest fraction.
- Thread form, pitch, plating, and hole tolerance are not represented by diameter conversion.
Illustrative measurement workflow; it does not claim that this value is a standard product size.
Editorial measurement check
Begin with the measured value and its stated resolution, rather than adding digits that the source instrument never established.
Where a nominal description is involved, obtain an actual dimension before making a fit or substitution decision.
Check both sides of the tolerance range after conversion; a matching center value can still hide an unacceptable limit.
Nearby comparison and substitution boundary
Rounding to the nearest 1/64 inch selects 1 17/64 inch only for measurements from 31.948438 mm up to (but not including) 32.345312 mm under half-up tie handling. For substitution, require an allowed dimensional deviation of at least 0.146875 mm and check the application-specific fit.
Candidate: 1 17/64 inch; absolute difference: 0.146875 mm.
