Examples
1
Consider that a premium camera lens has a focal length of 85 millimeters. Convert this focal length from millimeters to Inches.
Answer
Given:
Length in Millimeters = 85 mm
Converting Length from Millimeters to Inches...
The formula to convert from Millimeters to Inches is:
Length(Inches) = Length(Millimeters) / 25.4
Substitute given Length(Millimeters) = 85 in the above formula.
Length(Inches) = 85 / 25.4
Length(Inches) = 3.3465
Therefore, 85 mm is equal to 3.3465 in.
2
Consider that a luxury watch's thickness is 12 millimeters. Convert this thickness from millimeters to Inches.
Answer
Given:
Length in Millimeters = 12 mm
Converting Length from Millimeters to Inches...
The formula to convert from Millimeters to Inches is:
Length(Inches) = Length(Millimeters) / 25.4
Substitute given Length(Millimeters) = 12 in the above formula.
Length(Inches) = 12 / 25.4
Length(Inches) = 0.4724
Therefore, 12 mm is equal to 0.4724 in.

Millimeters
A millimeter (mm) is a unit of length in the International System of Units (SI). One millimeter is equivalent to 0.001 meters or approximately 0.03937 inches.
The millimeter is defined as one-thousandth of a meter, making it a precise measurement for small distances.
Millimeters are used worldwide to measure length and distance in various fields, including engineering, manufacturing, and everyday life. Many industries, especially those requiring high precision, have adopted the millimeter as a standard unit of measurement for small lengths.
Inches
An inch (symbol: in) is a unit of length used mainly in the United States, the United Kingdom, and Canada. One inch is equal to 2.54 centimeters.
The inch has origins in ancient times, originally based on the width of a human thumb. Its current definition, established in 1959, is exactly 2.54 centimeters.
Inches are commonly used to measure smaller lengths and distances, such as screen sizes and fabric lengths. Despite the widespread adoption of the metric system, the inch remains in use in these countries.
