Exact answer, measurement guidance, and nearby sizes
Direct answer and formula
15 mm is 0.5905511811 inches; the unrounded value is exactly 75/127 inch.
15 ÷ 25.4 = 0.5905511811 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 0.5906 in. The nearest 1/64-inch mark is 19/32 in, differing by 0.08125 mm; the nearest 1/32-inch mark is 19/32 in, differing by 0.08125 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
A scale model dimension is supplied in millimeters while an inch-based cutting plan is being prepared. For this route, 15 mm converts to 0.5905511811 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
Treat the source dimension as a controlled observation; preserve whether it represents a minimum, maximum, target, or nominal label.
Compare the smallest permitted opening with the largest permitted component whenever clearance, rather than center value, controls the decision.
On handoff, label which value is exact-derived and which value was deliberately rounded for execution.
Nearby comparison and substitution boundary
Rounding to the nearest 1/64 inch selects 19/32 inch only for measurements from 14.882812 mm up to (but not including) 15.279688 mm under half-up tie handling. For substitution, require an allowed dimensional deviation of at least 0.08125 mm and check the application-specific fit.
Candidate: 19/32 inch; absolute difference: 0.08125 mm.
