millimeters = inches × 25.4

This works because one inch is defined exactly as 25.4 millimeters by international agreement. Multiplying the inch value by 25.4 converts it directly into millimeters.

Example: Convert 6 inches to mm

• Start with 6 inches.
• Multiply 6 by 25.4.
• 6 × 25.4 = 152.4 mm.

Conversion Example

• Convert 3.5 inches to mm:
  • Multiply 3.5 × 25.4.
  • 3.5 × 25.4 = 88.9 mm.
  • The result is 88.9 millimeters.
• Convert 10 inches to mm:
  • Multiply 10 × 25.4.
  • 10 × 25.4 = 254 mm.
  • The answer is 254 millimeters.
• Convert 0.25 inches to mm:
  • Multiply 0.25 × 25.4.
  • 0.25 × 25.4 = 6.35 mm.
  • So, 0.25 inches equals 6.35 millimeters.
• Convert 15.7 inches to mm:
  • Multiply 15.7 × 25.4.
  • 15.7 × 25.4 = 398.78 mm.
  • 15.7 inches is 398.78 millimeters.

Conversion Definitions

Inches: An inch is a unit of length in the imperial and US customary systems, equal to exactly 2.54 centimeters. It is commonly used in the United States, Canada, and United Kingdom for measuring smaller objects, distances, or dimensions, especially in engineering and construction.

Millimeters (mm): Millimeter is a metric unit of length, equal to one thousandth of a meter. It is used worldwide for precise measurements in science, engineering, and everyday applications, providing a finer scale than centimeters or meters for small distances.

Conversion FAQs

Why is one inch exactly 25.4 millimeters?

The length of one inch was internationally standardized as 25.4 millimeters in 1959 by an agreement among English-speaking countries. This exact value replaced previous approximations, allowing consistent measurements worldwide. Before, inches varied slightly between countries.

Can I convert inches to millimeters by just multiplying by 2.5?

No, multiply by 2.5 is not accurate. The exact conversion is 25.4 millimeters per inch. Using 2.5 would cause errors, especially with larger values. Precision matters in technical fields, so multiplication by 25.4 is required for correct results.

Is there a quick mental math trick to convert inches to mm?

One way is to multiply the inch value by 25, then add 4% of the original inch value. For example, 6 inches × 25 = 150, plus 4% of 6 (which is 0.24), total about 150.24 mm, close to 152.4 mm. Though handy, this method is approximate.

Can negative inch values convert to millimeters?

Yes, negative inches represent lengths in the opposite direction or below zero reference points. Converting negative inches simply multiplies by 25.4, resulting in negative millimeters. This is useful in physics or coordinate measurements.

Are millimeters always more precise than inches?

Millimeters provide a smaller unit, so they often express measurements more precisely. Inches can be subdivided but usually in fractions, which may be less precise or harder to read. Millimeters suit scientific work where exact values matter.
