1mil in mil:PCB unit conversion

For personnel engaged in the PCB industry, it is inevitable to encounter various units of data. Conversion between various units is often needed, and it is often necessary to search for conversion values. For the convenience of PCB practitioners, personnel such as PCB engineering, PCB electronic engineers, etc. use and learn.1mil in milLine width/line pitch/plating thickness Common units: 1um (1 micron)=0.001 mm (0.001 mm)1um=0.03937mil1um=40uin (micro inches)1um (1 micron)=0.001mm1mil in mil=0.0254MM (Conversion reason: 1mil=1/1000inch=0.00254cm=0.0254mm)As we all know, 4mil/4mil=0.1mm/0.1mm line width line spacing 1mil in mm=25.4um 1mil=1000uin mil, sometimes also known as English wire II (common unit of copper thickness in pcb board) 1OZ (ounce)=35UM (micrometer)=28.35g/square foot1OZ (ounces)=28.35 grams, which is in English units1OZ (oz)=28.35 grams per square foot=35 um micrometer H/H=18 um/18 um micrometer double-sided plate with both sides of 18um copper thickness Three relatively uncommon bit conversions:1 foot=12 inches1 inch inch=1000 mil1ASD=1 ampere per square decimeter=10.76 amperes per square foot (1 square decimeter=10.76 square feet)1AM=1 ampere minute=60 coulombs, mainly used for precious metal electroplating such as gold plating1 square foot=9.29 square decimeters 1 gallon (English)=4.5 liters1 gallon US=3.785 liters1KHA=1000Ah1 ampere hour=3600 coulombs
