What sound does the letter µ make?

The letter µ (mu) doesn't have a sound of its own. It's a Greek letter that is often used in science and mathematics to represent different things.

Here are some examples of how it's used:

* µm stands for micrometer, a unit of length.

* µg stands for microgram, a unit of mass.

* µF stands for microfarad, a unit of capacitance.

It's important to note that the letter µ is pronounced like the letter "m" in the word "mute".
