What is the conversion from millimeters to inches

one inch equals approx 25 mm.

4.68

linear measure is a length measurement so if you have 14 inches ,that is linear measurement
if you have metric measure and you want to convert to inches,
14 " equals .355 meters or 335.0 millimeters
it is still linear measurement

An inch is defined as 2.54cm.
There are 10 millimeters in a centimeter.
Therefore there are 25.4mm in an inch.

So to convert millimeters to inches, divide by 25.4.

Good luck.

brake shoe thickness is measured in millimeters or inches, with the majority measured in millimeters. The minimum thickness a brake shoe should have will vary by manufacturer. However, between 2 and 3 millimeters is generally considered the minimum allowed thickness. Brake shoe thickness can be measured by removing the wheel and brake drum, and measuring the thickness of the brake shoe through the rivet holes.

Millimeter is a measure of length, liter is a measure of volume. There is no conversion between them. It's like asking "how many inches are in a gallon."
