Exact answer, measurement guidance, and nearby sizes
Direct answer and formula
The exact metric counterpart of 1 5/32 inches is 29.36875 mm under the international-inch definition.
37/32 × 25.4 = 29.36875 mm
Basis: 1 inch = 25.4 mm exactly (international inch definition)
Rounding, fractions, and tolerance
One-decimal display gives 29.4 mm. Rounding instead to the closest 0.5 mm produces 29.5 mm and 0.13125 mm error; use the coarser value only when the process tolerance permits it.
A nearby rounded size is acceptable only when its absolute difference is within the documented dimensional tolerance and all non-dimensional compatibility checks pass.
Parcel dimension entry
Use 1 5/32 inches in this parcel dimension entry workflow: an inch measurement of a parcel side must be entered in millimeters. Here the metric/imperial counterpart is 29.36875 mm. Follow the receiving form’s stated rounding rule and measure the outermost extent.
- Follow the receiving form’s stated rounding rule and measure the outermost extent.
- Compression and bulge can change the measured envelope.
Illustrative measurement workflow; it does not claim that this value is a standard product size.
Editorial measurement check
Separate the measured dimension from allowances such as kerf, coating, overlap, clearance, or trim.
A nearby catalog or tool size is only a candidate for review; numerical proximity does not establish interchangeability.
Retain one guard digit during calculation, then round once at the final communication or machine-entry step.
Nearby comparison and substitution boundary
The decision thresholds around 29.5 mm are 29.25 ≤ result < 29.75 mm. Confirm that a 0.13125 mm shift is acceptable before treating the rounded size as a substitute.
Candidate: 29.5 mm; absolute difference: 0.13125 mm.
