One of the things I struggle with is how to create electronic symbols in WordPress. For example, the ohm symbol (Ω) is probably the most frequent one I use, others are micro (µ) and square root (√). The table below gives the code portion that can be embedded in any HTML page, including WordPress. If you’re in WordPress, you must be in the HTML (not visual editor) mode.

Move your cursor to where you want to insert the Electronic symbols in WordPress type “&#CODE;” so “&#” must precede the code number and “;” must follow. That’s all there is to it. Note: for the codes that are less than 255, you can SOMETIMES enter it in the visual mode of WordPress by holding down the ALTernate key and typing the full 4-digit code on the Numeric Keypad (not the numbers above the letter keys).
Those keycodes that are less than 255 are considered ascii compatible. If there are others you’d like to see, drop me a line, I’ll see if what I can find.

Please let me know if you find this information on electronic symbols in WordPress. If you have favorite symbols or others that you use let me know and I’ll update this table of electronic symbols in WordPress.

Not exactly electrical engineering symbols, more like greek and mathematical fonts characters. For example, mho is the upside down omega symbol that is used a lot in EE and you would expect to have that in a EE oriented font. Still this is useful information.

OK, I’ll give that to you, only the ohm is devoted only to electronics… I’ll see if I can’t find what the code is for siemens which is the “new” or “approved” term for mho. Mho as the unit of conductance was simply the inverse of impedance and was just “ohm” backwards. Not sure why the went to siemens unless it was politically motivated. As an example, I’m old enough to remember that the Celsius temperature scale used to be called “centigrade” (“centi” deriving from 100) I’ve managed to find the ℧ symbol, but not what code to insert and show it in WordPress. Thanks for the note.
