Exact answer, measurement guidance, and nearby sizes
Direct answer and formula
7/32 inches is 5.55625 mm exactly because the international inch is exactly 25.4 mm.
7/32 × 25.4 = 5.55625 mm
Basis: 1 inch = 25.4 mm exactly (international inch definition)
Rounding, fractions, and tolerance
The converted value 5.55625 mm is exact. To one decimal it is 5.6 mm; the nearest 0.5 mm is 5.5 mm (difference 0.05625 mm), and the nearest whole millimeter is 6 mm (difference 0.44375 mm). Rounded metric sizes are not interchangeable unless that difference fits the tolerance budget.
A nearby rounded size is acceptable only when its absolute difference is within the documented dimensional tolerance and all non-dimensional compatibility checks pass.
Drill and clearance review
Use 7/32 inches in this drill and clearance review workflow: an inch drawing calls out a small hole or clearance and the available inspection tools read millimeters. Here the metric/imperial counterpart is 5.55625 mm. Convert the callout, then evaluate the specified clearance instead of automatically selecting the closest metric drill.
- Convert the callout, then evaluate the specified clearance instead of automatically selecting the closest metric drill.
- A cutting tool may produce a hole different from its nominal diameter.
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.
Choose display precision by comparing rounding error with the available tolerance budget, not by using a fixed number of decimals everywhere.
If a field measurement controls acceptance, reconcile it with the drawing value instead of overwriting either record.
Nearby comparison and substitution boundary
Nearest-0.5-mm rounding maps exact results from 5.25 mm up to (but not including) 5.75 mm to 5.5 mm with half-up ties. Using 5.5 mm as a physical substitute changes this dimension by 0.05625 mm; verify fit, thread, clearance, or process allowance as applicable.
Candidate: 5.5 mm; absolute difference: 0.05625 mm.
Questions about this exact conversion
What is the direct conversion for 7/32 inches?
7/32 inches is 5.55625 mm exactly because the international inch is exactly 25.4 mm.
How many digits should be kept for 7/32 inches?
The converted value 5.55625 mm is exact. To one decimal it is 5.6 mm; the nearest 0.5 mm is 5.5 mm (difference 0.05625 mm), and the nearest whole millimeter is 6 mm (difference 0.44375 mm). Rounded metric sizes are not interchangeable unless that difference fits the tolerance budget.
What can conversion alone not decide in this example?
Convert the callout, then evaluate the specified clearance instead of automatically selecting the closest metric drill. A cutting tool may produce a hole different from its nominal diameter.
Is the closest rounded size interchangeable with 7/32 inches?
Nearest-0.5-mm rounding maps exact results from 5.25 mm up to (but not including) 5.75 mm to 5.5 mm with half-up ties. Using 5.5 mm as a physical substitute changes this dimension by 0.05625 mm; verify fit, thread, clearance, or process allowance as applicable.
