Converting 1/16 inch to Millimeters

Converting 1/16 inch to Millimeters

Converting between imperial and metric units can be tricky, especially when dealing with fractions of an inch. This guide will walk you through how to easily convert 1/16 of an inch into millimeters. Understanding this conversion is useful for woodworkers, machinists, engineers, and anyone else working with precise measurements.

Key Takeaways

  • 1/16 of an inch equals 1.5875 millimeters when converted precisely.
  • To convert, multiply the number of inches by 25.4 to get millimeters.
  • Conversions between imperial and metric can be imprecise due to rounding.
  • Online conversion tools and charts provide quick references for converting fractions of an inch.

A Precise Conversion

To precisely convert 1/16 of an inch into millimeters:

  1. Take the fraction 1/16 and convert it to a decimal: 1/16 = 0.0625 inches
  2. Multiply the decimal inches by 25.4 (the conversion factor between inches and millimeters): 0.0625 * 25.4 = 1.5875 millimeters

Therefore, 1/16″ equals exactly 1.5875 mm when converted precisely.

Converting Larger Values

When converting a larger measurement with a fractional inch value, you simply multiply the whole number by 25.4 and add the fractional part converted to millimeters.

For example, to convert 5 3/16 inches:

  • Convert the fraction 3/16 to millimeters: 3/16 = 0.1875″ x 25.4 = 4.7625 mm
  • Multiply the whole inches by 25.4: 5 x 25.4 = 127 mm
  • Add the millimeter values: 127 + 4.7625 = 131.7625 mm

So 5 3/16″ converts to 131.7625 mm

Dealing with Rounding Errors

The conversion between fractions of an inch and millimeters often introduces small rounding errors. This is because the fractional measurements cannot be perfectly converted into decimal values.

For example, 1/4 inch is 0.25 inches. But 0.25 is a repeating decimal when converted to millimeters (6.35 mm).

These tiny errors add up when doing many conversions or working with precise tolerances. Be aware of potential rounding issues when converting.

Quick Reference Conversion Chart
