Scope of this reference
Convert common millimetre and inch measurements used at the bench. Use Guitar Setup Unit Conversion Reference to make a repeatable decision for this named task, not to impose one specification on every instrument.
Practical example
A measured 1.6 mm action is about 0.0630 inch and close to 4/64 inch. Keep 1.6 mm as the observed value if that matches the tool resolution; the fraction is a communication aid and does not add precision.
Record the conditions
For Guitar Setup Unit Conversion Reference, write down instrument type, tuning, installed strings, relevant hardware, climate when material, physical datum, unit, tool resolution, and the result before and after change. A result from this reference is comparable only when its method travels with the number.
Verification checklist
- For Guitar Setup Unit Conversion Reference, confirm the starting state and exact question.
- Repeat its critical measurements from the same reference.
- Compare its result with direct observation and applicable maker documentation.
- Change one reversible variable where the task permits.
- Retest the named symptom and preserve unresolved exceptions.
Related workflow
