Exact answer, measurement guidance, and nearby sizes
Direct answer and formula
46 mm is 1.811023622 inches; the unrounded value is exactly 230/127 inch.
46 ÷ 25.4 = 1.811023622 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 1.8110 in. The nearest 1/64-inch mark is 1 13/16 in, differing by 0.0375 mm; the nearest 1/32-inch mark is 1 13/16 in, differing by 0.0375 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.
Scale-model dimension
Consider this measurement task: a scale model dimension is supplied in millimeters while an inch-based cutting plan is being prepared. The working conversion is 46 mm = 1.811023622 inches. Retain enough decimal places that rounding stays below the model’s stated build allowance.
- Retain enough decimal places that rounding stays below the model’s stated build allowance.
- Kerf and assembly gaps must be budgeted independently.
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.
For repeated spacing, evaluate the end-position error after all intervals instead of judging one interval in isolation.
For a substitute, document the signed size difference and every non-dimensional compatibility check that remains open.
Nearby comparison and substitution boundary
Rounding to the nearest 1/64 inch selects 1 13/16 inch only for measurements from 45.839062 mm up to (but not including) 46.235938 mm under half-up tie handling. For substitution, require an allowed dimensional deviation of at least 0.0375 mm and check the application-specific fit.
Candidate: 1 13/16 inch; absolute difference: 0.0375 mm.
