What is a mil (thou)?

A mil, or thou, is a unit of length equal to one thousandth of an inch (0.001 in) used mainly to specify small thicknesses and tolerances in manufacturing.

What does centiinch mean?

A centiinch is a nonstandard length unit equal to one hundredth of an inch (0.01 in), often used informally to express moderate-precision dimensions.

Why convert mil to centiinch?

Converting from mil to centiinch helps express small measurements at a scale of hundredths of an inch rather than thousandths, making tolerances easier to interpret in some engineering contexts.

Common Use Cases

Specifying paint or coating thickness in automotive and industrial applications.
Defining printed circuit board (PCB) trace widths, spacing, and drill sizes in electronics.
Describing film, sheet, wire diameters, or shim/gap tolerances in mechanical fabrication.
Expressing moderate-precision dimensions in manufacturing and machining using hundredths of an inch.
Converting inch-based measurements to metric for engineering documentation or tooling.

Tips & Best Practices

Ensure that you understand the difference between thousandths and hundredths of an inch when working with small measurements.
Confirm unit definitions to avoid confusion since centiinch is a nonstandard unit.
Use this converter to help communicate measurements clearly within manufacturing or design teams.
Double-check conversions when preparing documentation for international use due to the informal status of centiinch.
Apply these conversions consistently to maintain precision in moderate-scale engineering tasks.

Limitations

The centiinch is not a standardized unit and might not be recognized in international standards.
Its informal use may cause misunderstandings if the unit is not clearly explained.
This converter applies only to the specific mil–centiinch relationship and does not cover other units.
