  1mil 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 often needed. It is often necessary to find the conversion value. For the convenience of PCB personnel, the following List the conversion values between various units for your reference. Both Chinese and English abbreviations are indicated. I believe the following unit conversions are worth a look.

1mil is equal to how many mm, 1um is equal to how many mm unit conversion formula(图1)

  Common unit conversion:

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

  1OZ (ounce) = 28.35 grams, this is the British 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 as wheat, but they are actually microinches)

  1um (1 micron)=0.001mm

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

  The result is: 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 micron

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

  1AM = 1 ampere minute = 60 coulombs, mainly used for precious metal plating such as gold plating

  1 square foot = 9.29 square decimetres

  1 gallon (imperial system) = 4.5 liters

  1 gallon US = 3.785 liters

  1KHA=1000Ah

  1 ampere hour = 3600 coulombs
