Converting 1/16 Inch to Millimeters

Converting 1/16 Inch to Millimeters

Converting between imperial and metric units is common for measurements of length in manufacturing, engineering, construction and do-it-yourself (DIY) projects. While inches are still widely used in the United States, much of the world uses the International System (SI) units including millimeters.

It helps to have a basic understanding of how to convert 1/16 inch to millimeters for measuring and calculating as needed. While conversion calculators and charts can be helpful, knowing the basic inch to millimeter conversion formula allows you to easily convert values in your head or on paper.

Key Takeaways

  • 1/16 inch is equal to 1.5875 mm when doing an exact conversion
  • For most practical purposes, 1/16 inch can be rounded to 1.5 or 1.6 mm
  • To convert, multiply the inch value by 25.4 to get millimeters
  • The millimeter is the standard metric unit for length, while the inch is commonly used in the United States
  • Knowing how to convert between inches and millimeters is useful for engineering, manufacturing, construction and DIY projects

What is a 1/16 Inch?

  • 1/16 of an inch is one sixteenth of an inch
  • Written numerically as 0.0625 inches
  • There are 16 portions of 1/16 inch in one full inch
  • A very small unit of length commonly used for precision measurements

1/16 inch represents a tiny unit of length equal to 0.0625 inches. As the name suggests, it is 1/16 of the standard unit of an inch. For example, if an inch were divided into 16 equal segments, one of those segments would be a 1/16 inch.

It is used for high-precision measurements where small differences in length or distance need to be accounted for. Some examples where 1/16 inch measurements come into play include:

  • Measuring machined parts and component fits in manufacturing
  • Gaps or joints in carpentry, doors, flooring and furniture
  • The width of lines drawn on paper or technical drawings
  • The thickness or gauge of small wires and metal sheets

So in summary, a 1/16 inch is a tiny sliver that helps account for small variations in linear measurements. It is one of the finer imperial measuring units commonly used.

Definition of a Millimeter

  • The millimeter (mm) is the standard metric unit for length
  • Equal to 1/1000 of a meter (3.28 feet)
  • There are 10 millimeters in 1 centimeter and 1000 millimeters in a meter
  • Used for measurements like length, width, height, depth and distance

The millimeter is the standard metric unit for measuring length in the International System of Units (SI). It is defined as one thousandth of a meter, with the meter being the SI base unit for length.

Some key facts about the millimeter:

  • 1000 mm = 1 meter
  • 10 mm = 1 centimeter
  • There are 25.4 millimeters in an inch

Millimeters are a practical unit for measuring on a small scale, such as for engineering drawings, manufacturing, medical applications, and consumer products. The millimeter allows for very precise measurements down to fractions of an inch in the imperial system.

Converting 1/16 Inch to Millimeters

There are a few ways to convert 1/16 inch to millimeters:

Exact Conversion

  • 1/16 inch = 1.5875 millimeters

To get an exact conversion, multiply the inch value by 25.4, since there are 25.4 mm in 1 inch:

  • 1/16 inch x 25.4 mm/inch = 1.5875 mm

This will give you the measurement in millimeters down to four decimal places when converting 1/16 inch.

Rounded Conversions

For most practical applications, the exact conversion is not necessary. 1/16 inch can be rounded to 1.5 mm or 1.6 mm depending on the level of precision required.

  • 1/16 inch ≈ 1.5 mm (rounded down)
  • 1/16 inch ≈ 1.6 mm (rounded up)

Rounding to 1.5 or 1.6 mm is sufficient when the level of precision does not require decimals. These rounded conversions are easy to remember for quick calculations.

Conversion Formula

The formula for converting any measurement in inches to millimeters is:

Millimeters = Inches x 25.4


  • Millimeters is the unit you want to convert to
  • Inches is the unit you are converting from
  • 25.4 is the conversion factor between inches and mm

Using this formula, you can plug in 1/16 inch to get the equivalent in millimeters:

1/16 inch x 25.4 = 1.5875 mm

This formula works for converting any inch value to mm.

Examples Converting 1/16 Inch to Millimeters

Here are some examples converting fractional inch values to mm:

Inch ValueMillimeters
1/4 inch6.35 mm
1/8 inch3.175 mm
1/16 inch1.5875 mm
1/32 inch0.7938 mm

And some examples rounding 1/16 inch:

  • 1/16 inch = ~1.6 mm
  • 3/16 inch = ~4.8 mm
  • 5/16 inch = ~8 mm

Being able to convert 1/16 inch to millimeters allows for more precise measurements and calculations in metric units. It is a useful conversion skill for engineering, manufacturing, construction and DIY applications.
