Whether you’re working on a home improvement project or tackling a more complicated engineering challenge, the need to convert between SAE (inch fractions) and metric (millimeters) comes up often. You’ll likely encounter the measurement 3/32″ in many applications.
So, what is 3/32″ in mm? Well, 3/32 inch is equal to 2.38125 mm.
In this article, we’ll show you how to convert 3/32″ to mm, explain the formula, and provide a conversion chart to make conversions easier.
The Formula Behind SAE to Metric Conversion
Converting from SAE (Society of Automotive Engineers) measurements to metric measurements is a common task. The metric system is a decimal-based system of measurement, and it’s used worldwide. SAE measurements use inches, which can be expressed as fractions.
The key to understanding the conversion is to know that there are 25.4 millimeters in one inch.
Converting Inch Fractions to Millimeters
Here’s a simple two-step method for converting inch fractions to millimeters:
- Convert the inch fraction to a decimal.
- Multiply the decimal by 25.4.
So, to convert 3/32″ to millimeters, you would first divide 3 by 32, which equals 0.09375. Then, you’d multiply 0.09375 by 25.4, which equals 2.38125 mm.
How to convert 3/32 inches to millimeters
Want to convert 3/32″ to millimeters? Here’s how to do it.
- First, convert the fraction (3/32) to a decimal. Divide 3 by 32 to get 0.09375.
- Then, multiply the decimal (0.09375) by the conversion factor, 25.4. So, 0.09375 x 25.4 = 2.38125.
- That means 3/32 of an inch equals 2.38125 millimeters.
SAE to Metric Conversion Chart and Common Values
When you’re working on a project that requires both SAE (U.S. Standard) and metric measurements, it’s helpful to have a conversion chart handy. Conversion charts give you a quick reference point for common conversions, and they’re particularly useful if you do these conversions often.
Here are some of the most common SAE to metric conversions:
- 1/32″ = 0.7938 mm
- 1/8″ = 3.175 mm
- 1″ = 25.4 mm
Remember, 3/32″ is equal to 2.38125 mm.
Applications and practical use cases
Converting SAE measurements (like inches) to metric measurements (like millimeters) is often a necessity in industries like engineering, manufacturing, automotive, and construction.
When might you need to convert 3/32″ to mm? Perhaps you’re selecting drill bit sizes, measuring the thickness of a material, or designing the components of a machine.
In these kinds of applications, accuracy is critical. A small error in conversion can result in parts that don’t fit or structures that aren’t sound.
