About Thou
A thou (also called mil) is one thousandth of an inch, equal to 0.0254 millimeters or 25.4 micrometers. This unit is commonly used in engineering and manufacturing in countries that use imperial measurements, particularly for specifying tolerances, wire gauges, and thin material thicknesses. For example, a standard plastic bag might be 1-2 thou thick, a sheet of paper is about 4 thou, and precision machined parts often have tolerances measured in thou. Electronic circuit board copper traces are typically 1.4 thou thick.
About Centimeters
A centimeter (cm) is one hundredth of a meter and one of the most frequently used units in daily life. A typical fingernail is about 1 cm wide, and a standard paperclip is about 3 cm long. This unit is particularly common in the metric system for measuring body height, clothing sizes, and small objects. In many countries, rulers in schools are marked in centimeters, making it a familiar unit for educational purposes. There are 2.54 centimeters in one inch.
