1mil in mm is equal to how many mm, 1um is equal to how many mm unit conversion formula

For those engaged in the PCB circuit board industry, it is inevitable that they will encounter various data units. Conversion between various units is also often needed. It is often necessary to find out the converted value. For the convenience of PCB personnel, the conversion values between various units are listed below for your reference. Both Chinese and English abbreviations are indicated. I believe the unit conversion below is worth a look.

Conversion of common units:

1OZ (ounces) = 35UM (microns) = 28.35 grams/square foot

1OZ (ounces) = 28.35 grams, this is the imperial unit

1OZ (ounce)=28.35g/square foot=35UM micron

1um (1 micron) = 0.001mm (0.001mm)

1um=0.03937mil

1um=40uin (some companies call microinches wheat, but they are actually microinches)

1um (1 micron) = 0.001mm

1mil in mm=0.0254MM (reason of conversion: 1mil=1/1000inch=0.00254cm=0.0254mm)

It can be concluded that: 4mil/4mil=0.1mm/0.1mm line width and line spacing

1mil=25.4um

1mil=1000uinmil mils sometimes become British silk

Relatively infrequent bit conversion:

1 foot = 12 inches

1 inch inch=1000 mil mil

H=18UM microns

1ASD=1 ampere/square decimetre=10.76 ampere/square foot (1 square decimetre=10.76 square foot)

1AM=1 Ampere Minute=60 Coulomb is mainly used for precious metal electroplating such as gold plating

1 square foot = 9.29 square decimetres

1 gallon (imperial) = 4.5 liters

1 gallon US = 3.785 liters

1KHA=1000Ah

1 ampere hour = 3600 coulombsz
