Exact answer, measurement guidance, and nearby sizes
Direct answer and formula
180 mm is 7.0866141732 inches; the unrounded value is exactly 900/127 inch.
180 ÷ 25.4 = 7.0866141732 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 7.0866 in. The nearest 1/64-inch mark is 7 3/32 in, differing by 0.18125 mm; the nearest 1/32-inch mark is 7 3/32 in, differing by 0.18125 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.
Machine travel check
Machine travel check is a useful context for 180 mm. The calculated counterpart is 7.0866141732 inches. Keep guard and approach allowance separate from the converted usable travel.
- Keep guard and approach allowance separate from the converted usable travel.
- Rated travel is not automatically the same as obstruction-free working space.
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.
Where a nominal description is involved, obtain an actual dimension before making a fit or substitution 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 7 3/32 inch only for measurements from 179.982812 mm up to (but not including) 180.379688 mm under half-up tie handling. For substitution, require an allowed dimensional deviation of at least 0.18125 mm and check the application-specific fit.
Candidate: 7 3/32 inch; absolute difference: 0.18125 mm.
