What is an Inch? (Definition, History & Usage)

An inch is a unit of length used in the British Imperial and US customary measurement systems. Historically, an inch was roughly based on the width of a human thumb. Today, it is officially defined as one-twelfth (1/12) of a foot.

Even though most countries follow the metric system, inches are still widely used in the United States, United Kingdom, and Canada. You’ll often see inches used to measure screen sizes, televisions, laptops, paper dimensions, furniture, construction materials, and height.

When converting inches to millimeters (mm), it is important to use the exact international value to ensure accuracy in engineering, manufacturing, and daily measurements.

What is a Millimeter? (mm Explained Simply)

A millimeter (mm) is a metric unit of length in the International System of Units (SI). One millimeter equals one-thousandth (1/1000) of a meter.

Millimeters are commonly used worldwide for precise measurements in science, engineering, manufacturing, mechanics, medical tools, and everyday objects. Because the metric system is standardized internationally, converting inches to millimeters ensures consistent and accurate results across countries.

If you need high precision, converting inch to mm is often preferred because millimeters allow smaller and more exact measurements.

Inches to Millimeters Conversion Formula (With Examples)

The exact formula for converting inches to millimeters is:

Millimeters = Inches × 25.4

This is because 1 inch is officially defined as exactly 25.4 millimeters. This value was internationally standardized in 1959 to ensure consistent measurements.

Here are some quick worked examples:

  • 2 inches to mm: 2 × 25.4 = 50.8 mm
  • 5 inches to mm: 5 × 25.4 = 127 mm
  • 0.5 inch to mm: 0.5 × 25.4 = 12.7 mm
  • 10 inches to mm: 10 × 25.4 = 254 mm

Simply multiply any inch value by 25.4 to get the exact millimeter equivalent.
