1/2 NPT Thread to MM Conversion
The 1/2 NPT thread is a common thread size used in various industries, including piping, plumbing, and engineering. However, it can be challenging to convert this thread size to a metric equivalent, such as millimeters (mm). In this article, we will discuss the conversion of 1/2 NPT thread to mm and provide a clear understanding of the process.
What is NPT Thread?
The National Pipe Taper (NPT) thread is a standard thread size used in piping and tubing applications. It is measured in inches, with the size indicating the outside diameter of the pipe or tube. The 1/2 NPT thread has an outside diameter of 0.840 inches (21.34 mm) and 14 threads per inch.
Conversion of 1/2 NPT Thread to MM
To convert the 1/2 NPT thread to mm, we need to consider the outside diameter of the pipe or tube. The outside diameter of a 1/2 NPT thread is 21.34 mm.
Here is a conversion chart to help you convert 1/2 NPT thread to mm:
| NPT Size | Outside Diameter (in) | Outside Diameter (mm) |
|---|---|---|
| 1/2 | 0.840 | 21.34 |
Importance of Accurate Conversion
Accurate conversion of 1/2 NPT thread to mm is crucial in various industries, including:
