8 Ways to Type Mu/Micro symbol in Word and Mac?

Micro is the 12th letter of the Greek alphabet (U+00B5) which is primarily used in physics. Some of the quantities are very large or small, so we use prefixes to express these quantities.

It is also a prefix that is useful to express very small quantities. Its value is (0.00001).
For example, if you have a small number like 0.000025, you can write it 2.5µ.

In Microsoft windows or Mac, we don’t have special characters like backwards 3, sigma, degree sign, and micro symbol on the keyboard, but we can insert them using alternative codes. In Microsoft windows, Press and hold the Alt key and then type 0181. It will convert it into a micron symbol. You must have a numeric keyboard to use this code, or you can enable a numeric keyboard by pressing Fn and Numlock key. On Mac, you can insert it by using the option + M. Press the Option and M together. It will convert it into micro.
