A mil is one thousandth of an inch or 0.0001 inch.
Hence, there are 1000 mils in one inch. Mils are often used as measurement in manufacturing in countries that are on the English standard. Such as the United States and some countries in South America. The rest of the world uses the metric system or meters.
Mils seem to have taken hold in the manufacturing of printed circuit boards. Many countries that are using the metric system still use English Mils for electronic manufacturing.
Doing a quick search for PCB manufacturing or manufactures you will see the term Mils all over the place. The reason for this is the United States was the dominate leader in electronic manufacturing when it was in its infancy.
Keeping it in the electronic industry is the cost of developing manufacturing equipment using the metric system to replace current English equipment.

What is mils in measurement?
one one thousandth of an inch
How many mils in a inch?
Mil means 1/1000 of an inch.
80 mils is equivilant to what fraction of an inch?
80 mils =80/1000 inch, or 2/25 inch
How thick is 75 mil as a fraction?
- mils are a unit of measure - 1 mil is 1/1000 of an inch thick - 75 mils is 75/1000 of an inch, or .075 inch
90 mils is equivilant to what fraction of an inch?
In the United States, One Mil is understood to be one one thousandth of an inch, or 0.001 inches. Mils are frequently used in measuring plastic, film, and sheet materials in applications that do not use the metric system.90 mils is equal to 0.090 inches, or 90/1000ths of an inch, which reduces to 9/100ths of an inch.However, fractional parts of inches are normally measured in powers of two (for example, 1/4 inch, 1/8 inch, 1/16 inch, and so on). In this case, we cannot get an exact answer, but we can come acceptably close.If using thirty-seconds of an inch (1/32), you can get pretty close to 90 mils. 3/32 of an inch is equal to 0.09375 inches, or approximately 94 mils. For most applications, that's probably accurate enough.For better accuracy than that, you would need to measure in 256ths. 23/256ths of an inch is approximately 0.0898 inches, which is within one mil tolerance of 90 mils.
