Conversion Formula
To convert millimeters to inches, you divide the length value in millimeters by 25.4. This works because exactly 25.4 millimeters make up one inch.
Formula:
inches = millimeters ÷ 25.4
Why it works: Millimeter and inch are both units of length but from different measurement systems—metric and imperial respectively. Since one inch equals 25.4 millimeters, dividing by 25.4 converts the metric length into imperial.
Example calculation for 2.0 mm:
- Start with 2.0 mm
- Divide by 25.4: 2.0 ÷ 25.4 = 0.07874 (rounded)
- So, 2.0 mm is about 0.0787 inches.
Conversion Example
- 5.5 mm to inches:
- Take 5.5 mm
- Calculate 5.5 ÷ 25.4 = approximately 0.2165 inches
- Result is 0.2165 inches
- 10 mm to inches:
- Start with 10 mm
- Divide by 25.4: 10 ÷ 25.4 = 0.3937 inches
- So, 10 mm equals 0.3937 inches
- 0.1 mm to inches:
- Take 0.1 mm
- Calculate 0.1 ÷ 25.4 = 0.00394 inches
- Result is 0.0039 inches rounded
- 15 mm to inches:
- Begin with 15 mm
- Divide by 25.4: 15 ÷ 25.4 = 0.5906 inches
- So, 15 mm equals 0.5906 inches

Conversion Definitions
mm: Millimeter is a metric unit of length equal to one thousandth of a meter. It is often used to measure small distances or thicknesses in engineering, manufacturing, and everyday objects, providing finer precision than centimeters or meters.
inches: Inch is a unit of length from the imperial system, equal to 1/12 of a foot or exactly 25.4 millimeters. It is commonly used in the United States and other countries for measuring small lengths, thickness, or screen sizes.
Conversion FAQs
Why do we divide millimeters by 25.4 to get inches?
The number 25.4 represents the exact millimeter length of one inch. Dividing by 25.4 converts millimeters, a metric unit, into inches from the imperial system by scaling down the value proportionally. This makes the two measurement systems compatible for conversion.
Can the conversion from mm to inches cause rounding errors?
Yes, because many millimeter values convert to decimal inches that keep going indefinitely. When rounding to a certain number of decimal places, small errors can appear. However, rounding to four decimal places or more keeps accuracy sufficient for most uses.
Is the millimeter to inch conversion formula the same for negative values?
Yes, the formula applies the same for negative lengths, which could represent direction or displacement. Dividing the negative millimeter by 25.4 gives the negative inch equivalent, preserving the sign.
Are inches and millimeters used in different industries?
Millimeters are popular in science, engineering, and countries using metric system. Inches are common in the US, construction, and manufacturing. Knowing conversion helps work across both systems, especially when reading specifications or blueprints.
Does the conversion change if you want to convert thickness instead of length?
No, thickness is still a length measure. Whether thickness or length, millimeters to inches conversion stays the same, as both measure distance along a single dimension.
