How to Convert Inches to Millimeters?

1 inch is equal to 25.4 millimeters:

1″ = 25.4 mm

The length measured in millimeters (mm) can be derived by multiplying the length measured in inches (″) by a factor of 25.4:

d_(mm) = d_(inch) * 25.4

FACTS:

1) A millimeter (abbreviated as mm) represents a unit of length within the metric system, also known as the International System of Units (SI). This minuscule measurement serves as the smallest unit on metric rulers and tape measures. To put it in perspective, a single millimeter constitutes one-tenth of a centimeter and a mere 1/1000th of a meter in length.

2) An inch (symbol: in) is a unit of length in the Imperial and U.S. Customary systems of measurement. The inch is most commonly used in the United States, Canada, and the United Kingdom.

Examples

Example 1:

Consider a standard North American electrical outlet plate, which typically measures 2.75 inches in width. To convert this measurement to millimeters, we can use the formula:

Width (mm) = Width (inches) * 25.4

Plugging in the value, we get:

Width (mm) = 2.75 inches * 25.4 = 69.85 mm

So, the width of a North American electrical outlet plate is approximately 69.85 millimeters. This conversion is essential for electricians and engineers when designing electrical fixtures and components to ensure precise and compatible fittings

Example 2:

In engineering, converting measurements between inches and millimeters is a common practice. To perform this conversion, one can use the following formula:

d_(mm) = d_(inch) * 25,4

For instance, if you have a bolt with a length of 2.5 inches and want to express it in millimeters, you can calculate it as follows:

Millimeters = 2.5 inches * 25.4 = 63.5 mm

So, a bolt measuring 2.5 inches is equivalent to 63.5 millimeters, a vital conversion in the world of engineering and manufacturing.

How Many Inches in a Millimeter?

One millimeter is equal to 0,03937 inches:

1mm = 1mm / 25,4mm/in = 0,03937 in

How Many Millimeters in an Inch?

One inch is equal to 25,4 millimeters:

1 in = 25,4 mm / in * 1 in = 25,4 mm
